有效地替换字符串中的所有重音字符?

如何解决《有效地替换字符串中的所有重音字符?》经验,为你挑选了10个好方法。

对于一个穷人在客户端实现近似校正正确的排序,我需要一个JavaScript函数来在字符串中进行有效的单个字符替换.

这就是我的意思(请注意,这适用于德语文本,其他语言的排序方式不同):

native sorting gets it wrong: a b c o u z ä ö ü
collation-correct would be:   a ä b c o ö u ü z

基本上,我需要将所有出现的给定字符串的"ä"替换为"a"(依此类推).这样,本机排序的结果将非常接近用户期望的结果(或数据库将返回的内容).

其他语言有这样的设施:Python提供str.translate(),在Perl中tr/…/…/,XPath有一个函数translate(),ColdFusion有ReplaceList().但是JavaScript呢?

这就是我现在所拥有的.

// s would be a rather short string (something like 
// 200 characters at max, most of the time much less)
function makeSortString(s) {
  var translate = {
    "ä": "a", "ö": "o", "ü": "u",
    "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
  };
  var translate_re = /[öäüÖÄÜ]/g;
  return ( s.replace(translate_re, function(match) { 
    return translate[match]; 
  }) );
}

首先,我不喜欢每次调用函数时都重建正则表达式的事实.我认为关闭可以在这方面提供帮助,但我似乎并没有因为某些原因而得到它的支持.

有人能想到更高效的东西吗?


以下答案分为两类:

    不同程度的完整性和效率的字符串替换功能(我最初询问的内容)

    一晚一提的 String#localeCompare,它被广泛JS引擎之间的支持,可能这一类的问题,更完美地解决.

一些例子:

false
> "Pique".isLatin();

> "Piqué".latinise().isLatin();
true

更改字符串原型,这是主要的不良做法.我必须更新它.不管怎么说,还是要谢谢你 (3认同)

这一行有什么意义:`String.prototype.latinize = String.prototype.latinise;`? (2认同)

我不能说你正在尝试用函数本身做什么,但是如果你不喜欢每次构建的正则表达式,这里有两个解决方案和一些关于每个的注意事项.

这是一种方法:

function makeSortString(s) {
  if(!makeSortString.translate_re) makeSortString.translate_re = /[öäüÖÄÜ]/g;
  var translate = {
    "ä": "a", "ö": "o", "ü": "u",
    "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
  };
  return ( s.replace(makeSortString.translate_re, function(match) { 
    return translate[match]; 
  }) );
}

这显然会使正则表达式成为函数本身的属性.你唯一不喜欢这个(或者你可能,我猜它取决于)是正则表达式现在可以在函数体外修改.所以,有人可以这样做来修改interally使用的正则表达式:

makeSortString.translate_re = /[a-z]/g;

所以,有这个选择.

获取闭包,从而阻止某人修改正则表达式的一种方法是将其定义为匿名函数赋值,如下所示:

var makeSortString = (function() {
  var translate_re = /[öäüÖÄÜ]/g;
  return function(s) {
    var translate = {
      "ä": "a", "ö": "o", "ü": "u",
      "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
    };
    return ( s.replace(translate_re, function(match) { 
      return translate[match]; 
    }) );
  }
})();

希望这对你有用.


更新:它是早期的,我不知道为什么我之前没有看到明显的,但将translate对象也放在一个闭包中也可能有用:

var makeSortString = (function() {
  var translate_re = /[öäüÖÄÜ]/g;
  var translate = {
    "ä": "a", "ö": "o", "ü": "u",
    "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
  };
  return function(s) {
    return ( s.replace(translate_re, function(match) { 
      return translate[match]; 
    }) );
  }
})();

匈牙利regexp的charset:`var translate_re =/[éáűőúöüóíÉÁŰPŐÚÖÜÓÍ]/g; var translate = {"é":"e","á":"a","ű":"u","ő":"o","ú":"u","ö":"o ","ü":"u","ó":"o","í":"i","É":"E","Á":"A","Ű":"U", "Ő":"O","Ú":"U","Ö":"O","Ü":"U","Ó":"O","Í":"我"}; (7认同)

这种口音的正确术语是变音符号.谷歌搜索这个术语后,我发现这个功能是其中的一部分backbone.paginator.它有一个非常完整的变音符号系列,并用最直观的ascii字符替换它们.我发现这是目前最完整的Javascript解决方案.

只需要规范化链并运行替换代码:

var str = "Letras Á É Í Ó Ú Ñ - á é í ó ú ñ...";
console.log (str.normalize ("NFKD").replace (/[\u0300-\u036F]/g, ""));
// Letras A E I O U N - a e i o u n...

请参阅normalize

然后你可以使用这个功能:

function noTilde (s) {
    if (s.normalize != undefined) {
        s = s.normalize ("NFKD");
    }
    return s.replace (/[\u0300-\u036F]/g, "");
}

IE中不支持此功能:( (2认同)

使用ES2015/ES6 String.Prototype.Normalize(),

const str = "Crème Brulée"
str.normalize('NFD').replace(/[\u0300-\u036f]/g, "")
> 'Creme Brulee'

这里发生了两件事:

    normalize()荷兰国际集团到NFD的Unicode标准形式分解组合字形为简单的人的组合.在èCrème端起来表示为e+ ?.

    使用正则表达式字符类来匹配U + 0300→U + 036F范围,现在可以g轻易地去除变音符号,Unicode标准可以方便地将其组合为组合变音符号 Unicode块.

请参阅性能测试评论.

或者,如果您只是想要排序

Intl.Collat​​or现在有足够的支持〜85 %,这里也有填充剂,但我还没有测试过.

const c = new Intl.Collator();
['creme brulee', 'crème brulée', 'crame brulai', 'crome brouillé',
'creme brulay', 'creme brulfé', 'creme bruléa'].sort(c.compare)
[ 'crame brulai','creme brulay','creme bruléa','creme brulee',
'crème brulée','creme brulfé','crome brouillé' ]


['creme brulee', 'crème brulée', 'crame brulai', 'crome brouillé'].sort((a,b) => a>b)
["crame brulai", "creme brulee", "crome brouillé", "crème brulée"]

基于Jason Bunting的解决方案,这是我现在使用的.

整个问题是jQuery tablesorter插件:对于(几乎正确的)使用tablesorter插件排序非英语表,有必要使用自定义textExtraction函数.

这个:

将最常见的重音字母翻译成不重音的字母(支持的字母列表很容易扩展)

将德语格式('dd.mm.yyyy')的日期更改为可识别的格式('yyyy-mm-dd')

小心以UTF-8编码保存JavaScript文件,否则它将无法正常工作.

// file encoding must be UTF-8!
function getTextExtractor()
{
  return (function() {
    var patternLetters = /[öäüÖÄÜáàâéèêúùûóòôÁÀÂÉÈÊÚÙÛÓÒÔß]/g;
    var patternDateDmy = /^(?:\D+)?(\d{1,2})\.(\d{1,2})\.(\d{2,4})$/;
    var lookupLetters = {
      "ä": "a", "ö": "o", "ü": "u",
      "Ä": "A", "Ö": "O", "Ü": "U",
      "á": "a", "à": "a", "â": "a",
      "é": "e", "è": "e", "ê": "e",
      "ú": "u", "ù": "u", "û": "u",
      "ó": "o", "ò": "o", "ô": "o",
      "Á": "A", "À": "A", "Â": "A",
      "É": "E", "È": "E", "Ê": "E",
      "Ú": "U", "Ù": "U", "Û": "U",
      "Ó": "O", "Ò": "O", "Ô": "O",
      "ß": "s"
    };
    var letterTranslator = function(match) { 
      return lookupLetters[match] || match;
    }

    return function(node) {
      var text = $.trim($(node).text());
      var date = text.match(patternDateDmy);
      if (date)
        return [date[3], date[2], date[1]].join("-");
      else
        return text.replace(patternLetters, letterTranslator);
    }
  })();
}

你可以像这样使用它:

$("table.sortable").tablesorter({ 
  textExtraction: getTextExtractor()
}); 

我仍然有排序问题,例如:Šalat,Sup.这是不正确的顺序所以我做了这样的事情 - "Š":"Szz","š":"szz",应该几乎100%有效 (2认同)

我认为这可能会更清洁/更好(虽然我没有测试它的性能):

String.prototype.stripAccents = function() {
    var translate_re = /[àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ]/g;
    var translate = 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY';
    return (this.replace(translate_re, function(match){
        return translate.substr(translate_re.source.indexOf(match)-1, 1); })
    );
};

或者,如果你仍然过于担心表现,那么让我们两全其美:

String.prototype.stripAccents = function() {
    var in_chrs =  'àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ',
        out_chrs = 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY', 
        transl = {};
    eval('var chars_rgx = /['+in_chrs+']/g');
    for(var i = 0; i < in_chrs.length; i++){ transl[in_chrs.charAt(i)] = out_chrs.charAt(i); }
    return this.replace(chars_rgx, function(match){
        return transl[match]; });
};

编辑(@Tomalak)

我很欣赏这个主意.但是,如下面的评论中所述,实施有几个问题.

以下是我将如何实现它.

var stripAccents = (function () {
  var in_chrs   = 'àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ',
      out_chrs  = 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY', 
      chars_rgx = new RegExp('[' + in_chrs + ']', 'g'),
      transl    = {}, i,
      lookup    = function (m) { return transl[m] || m; };

  for (i=0; i

抱歉,此代码有几处出错.首先,它不恰当地使用`eval()`.有新的RegExp()`.其次,它修改了String原型.修改内置数据类型非常受欢迎.第三,该函数在每次调用时都运行for-each-character循环.这是我一开始就试图避免的.这意味着它以牺牲性能为代价来修复可读性,我认为这是一个糟糕的权衡.我很欣赏这个想法,但执行不是很理想.:) (3认同)

如果您正在寻找一种将重音字符转换为非重音字符的方法,而不是通过一点点的方式对重音字符进行排序,可以操纵String.localeCompare函数来查找与之相匹配的基本拉丁字符.扩展的.例如,您可能希望从页面标题中生成一个人性化的url slug.如果是这样,你可以这样做:

var baseChars = [];
for (var i = 97; i < 97 + 26; i++) {
  baseChars.push(String.fromCharCode(i));

//if needed, handle fancy compound characters
baseChars = baseChars.concat('ss,aa,ae,ao,au,av,ay,dz,hv,lj,nj,oi,ou,oo,tz,vy'.split(','));

  //if (!('noMatchChar' in opts)) opts.noMatchChar = '';
  if (!('locale' in opts)) opts.locale = 'en';

  var cOpts = {sensitivity: 'base'};

  //exit early for any non-alphabetical character
  if (c.localeCompare('9', opts.locale, cOpts) <= 0) return opts.nonAlphaChar === undefined ? c : opts.nonAlphaChar;

  for (var i = 0; i < baseChars.length; i++) {
    var baseChar = baseChars[i];

    var comp = c.localeCompare(baseChar, opts.locale, cOpts);

}

function latinify(str, opts) {
  return str.replace(/[^\w\s\d]/g, function(c) {
    return toBaseChar(c, opts);
  })
}

// Example:
console.log(latinify('?eština Ts?hesen?stsestotse Tshiven?a Emigliàn–Rumagnòl Slovenš?ina Português Ti?ng Vi?t Straße'))

// "Cestina Tsehesenestsestotse Tshivenda Emiglian–Rumagnol Slovenscina Portugues Tieng Viet Strasse"

这应该表现得很好,但如果需要进一步优化,可以使用二进制搜索localeCompare作为比较器来定位基本字符.请注意,保留了大小写,并且选项允许保留,替换或删除不按字母顺序排列的字符,或者没有匹配的拉丁字符,可以替换它们.此实现更快,更灵活,并且应在添加新字符时使用.缺点是如果需要支持复合字符,必须特别处理像'ꝡ'这样的复合字符.

String.prototype.latinise=function(){return this.replace(/[^A-Za-z0-9\[\] ]/g,function(a){return Latinise.latin_map[a]||a})};
String.prototype.latinize=String.prototype.latinise;
String.prototype.isLatin=function(){return this==this.latinise()}

一些例子:

> "Piqué".latinize();
"Pique"
> "Piqué".isLatin();
false
> "Pique".isLatin();
true
> "Piqué".latinise().isLatin();
true


更改字符串原型,这是主要的不良做法.我必须更新它.不管怎么说,还是要谢谢你
这一行有什么意义:`String.prototype.latinize = String.prototype.latinise;`?

2> Jason Buntin..:

我不能说你正在尝试用函数本身做什么,但是如果你不喜欢每次构建的正则表达式,这里有两个解决方案和一些关于每个的注意事项.

这是一种方法:

function makeSortString(s) {
  if(!makeSortString.translate_re) makeSortString.translate_re = /[öäüÖÄÜ]/g;
  var translate = {
    "ä": "a", "ö": "o", "ü": "u",
    "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
  };
  return ( s.replace(makeSortString.translate_re, function(match) { 
    return translate[match]; 
  }) );
}

这显然会使正则表达式成为函数本身的属性.你唯一不喜欢这个(或者你可能,我猜它取决于)是正则表达式现在可以在函数体外修改.所以,有人可以这样做来修改interally使用的正则表达式:

makeSortString.translate_re = /[a-z]/g;

所以,有这个选择.

获取闭包,从而阻止某人修改正则表达式的一种方法是将其定义为匿名函数赋值,如下所示:

var makeSortString = (function() {
  var translate_re = /[öäüÖÄÜ]/g;
  return function(s) {
    var translate = {
      "ä": "a", "ö": "o", "ü": "u",
      "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
    };
    return ( s.replace(translate_re, function(match) { 
      return translate[match]; 
    }) );
  }
})();

希望这对你有用.


更新:它是早期的,我不知道为什么我之前没有看到明显的,但将translate对象也放在一个闭包中也可能有用:

var makeSortString = (function() {
  var translate_re = /[öäüÖÄÜ]/g;
  var translate = {
    "ä": "a", "ö": "o", "ü": "u",
    "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
  };
  return function(s) {
    return ( s.replace(translate_re, function(match) { 
      return translate[match]; 
    }) );
  }
})();


匈牙利regexp的charset:`var translate_re =/[éáűőúöüóíÉÁŰPŐÚÖÜÓÍ]/g; var translate = {"é":"e","á":"a","ű":"u","ő":"o","ú":"u","ö":"o ","ü":"u","ó":"o","í":"i","É":"E","Á":"A","Ű":"U", "Ő":"O","Ú":"U","Ö":"O","Ü":"U","Ó":"O","Í":"我"};

这种口音的正确术语是变音符号.谷歌搜索这个术语后,我发现这个功能是其中的一部分backbone.paginator.它有一个非常完整的变音符号系列,并用最直观的ascii字符替换它们.我发现这是目前最完整的Javascript解决方案.

只需要规范化链并运行替换代码:

var str = "Letras Á É Í Ó Ú Ñ - á é í ó ú ñ...";
console.log (str.normalize ("NFKD").replace (/[\u0300-\u036F]/g, ""));
// Letras A E I O U N - a e i o u n...

请参阅normalize

然后你可以使用这个功能:

function noTilde (s) {
    if (s.normalize != undefined) {
        s = s.normalize ("NFKD");
    }
    return s.replace (/[\u0300-\u036F]/g, "");
}


IE中不支持此功能:(

5> 小智..:

/sf/ask/17360801/

使用ES2015/ES6 String.Prototype.Normalize(),

const str = "Crème Brulée"
str.normalize('NFD').replace(/[\u0300-\u036f]/g, "")
> 'Creme Brulee'

这里发生了两件事:

    normalize()荷兰国际集团到NFD的Unicode标准形式分解组合字形为简单的人的组合.在èCrème端起来表示为e+ ?.

    使用正则表达式字符类来匹配U + 0300→U + 036F范围,现在可以g轻易地去除变音符号,Unicode标准可以方便地将其组合为组合变音符号 Unicode块.

请参阅性能测试评论.

或者,如果您只是想要排序

Intl.Collat​​or现在有足够的支持〜85 %,这里也有填充剂,但我还没有测试过.

const c = new Intl.Collator();
['creme brulee', 'crème brulée', 'crame brulai', 'crome brouillé',
'creme brulay', 'creme brulfé', 'creme bruléa'].sort(c.compare)
[ 'crame brulai','creme brulay','creme bruléa','creme brulee',
'crème brulée','creme brulfé','crome brouillé' ]


['creme brulee', 'crème brulée', 'crame brulai', 'crome brouillé'].sort((a,b) => a>b)
["crame brulai", "creme brulee", "crome brouillé", "crème brulée"]



6> Tomalak..:

基于Jason Bunting的解决方案,这是我现在使用的.

整个问题是jQuery tablesorter插件:对于(几乎正确的)使用tablesorter插件排序非英语表,有必要使用自定义textExtraction函数.

这个:

将最常见的重音字母翻译成不重音的字母(支持的字母列表很容易扩展)

将德语格式('dd.mm.yyyy')的日期更改为可识别的格式('yyyy-mm-dd')

小心以UTF-8编码保存JavaScript文件,否则它将无法正常工作.

// file encoding must be UTF-8!
function getTextExtractor()
{
  return (function() {
    var patternLetters = /[öäüÖÄÜáàâéèêúùûóòôÁÀÂÉÈÊÚÙÛÓÒÔß]/g;
    var patternDateDmy = /^(?:\D+)?(\d{1,2})\.(\d{1,2})\.(\d{2,4})$/;
    var lookupLetters = {
      "ä": "a", "ö": "o", "ü": "u",
      "Ä": "A", "Ö": "O", "Ü": "U",
      "á": "a", "à": "a", "â": "a",
      "é": "e", "è": "e", "ê": "e",
      "ú": "u", "ù": "u", "û": "u",
      "ó": "o", "ò": "o", "ô": "o",
      "Á": "A", "À": "A", "Â": "A",
      "É": "E", "È": "E", "Ê": "E",
      "Ú": "U", "Ù": "U", "Û": "U",
      "Ó": "O", "Ò": "O", "Ô": "O",
      "ß": "s"
    };
    var letterTranslator = function(match) { 
      return lookupLetters[match] || match;
    }

    return function(node) {
      var text = $.trim($(node).text());
      var date = text.match(patternDateDmy);
      if (date)
        return [date[3], date[2], date[1]].join("-");
      else
        return text.replace(patternLetters, letterTranslator);
    }
  })();
}

你可以像这样使用它:

$("table.sortable").tablesorter({ 
  textExtraction: getTextExtractor()
}); 


我仍然有排序问题,例如:Šalat,Sup.这是不正确的顺序所以我做了这样的事情 - "Š":"Szz","š":"szz",应该几乎100%有效

7> Martin_Lakes..:

我认为这可能会更清洁/更好(虽然我没有测试它的性能):

String.prototype.stripAccents = function() {
    var translate_re = /[àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ]/g;
    var translate = 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY';
    return (this.replace(translate_re, function(match){
        return translate.substr(translate_re.source.indexOf(match)-1, 1); })
    );
};

或者,如果你仍然过于担心表现,那么让我们两全其美:

String.prototype.stripAccents = function() {
    var in_chrs =  'àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ',
        out_chrs = 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY', 
        transl = {};
    eval('var chars_rgx = /['+in_chrs+']/g');
    for(var i = 0; i < in_chrs.length; i++){ transl[in_chrs.charAt(i)] = out_chrs.charAt(i); }
    return this.replace(chars_rgx, function(match){
        return transl[match]; });
};

编辑(@Tomalak)

我很欣赏这个主意.但是,如下面的评论中所述,实施有几个问题.

以下是我将如何实现它.

var stripAccents = (function () {
  var in_chrs   = 'àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ',
      out_chrs  = 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY', 
      chars_rgx = new RegExp('[' + in_chrs + ']', 'g'),
      transl    = {}, i,
      lookup    = function (m) { return transl[m] || m; };

  for (i=0; i


抱歉,此代码有几处出错.首先,它不恰当地使用`eval()`.有新的RegExp()`.其次,它修改了String原型.修改内置数据类型非常受欢迎.第三,该函数在每次调用时都运行for-each-character循环.这是我一开始就试图避免的.这意味着它以牺牲性能为代价来修复可读性,我认为这是一个糟糕的权衡.我很欣赏这个想法,但执行不是很理想.:)

9> undefined..:

如果您正在寻找一种将重音字符转换为非重音字符的方法,而不是通过一点点的方式对重音字符进行排序,可以操纵String.localeCompare函数来查找与之相匹配的基本拉丁字符.扩展的.例如,您可能希望从页面标题中生成一个人性化的url slug.如果是这样,你可以这样做:

var baseChars = [];
for (var i = 97; i < 97 + 26; i++) {
  baseChars.push(String.fromCharCode(i));
}

//if needed, handle fancy compound characters
baseChars = baseChars.concat('ss,aa,ae,ao,au,av,ay,dz,hv,lj,nj,oi,ou,oo,tz,vy'.split(','));

function isUpperCase(c) { return c !== c.toLocaleLowerCase() }

function toBaseChar(c, opts) {
  opts = opts || {};
  //if (!('nonAlphaChar' in opts)) opts.nonAlphaChar = '';
  //if (!('noMatchChar' in opts)) opts.noMatchChar = '';
  if (!('locale' in opts)) opts.locale = 'en';

  var cOpts = {sensitivity: 'base'};

  //exit early for any non-alphabetical character
  if (c.localeCompare('9', opts.locale, cOpts) <= 0) return opts.nonAlphaChar === undefined ? c : opts.nonAlphaChar;

  for (var i = 0; i < baseChars.length; i++) {
    var baseChar = baseChars[i];

    var comp = c.localeCompare(baseChar, opts.locale, cOpts);
    if (comp == 0) return (isUpperCase(c)) ? baseChar.toUpperCase() : baseChar;
  }

  return opts.noMatchChar === undefined ? c : opts.noMatchChar;
}

function latinify(str, opts) {
  return str.replace(/[^\w\s\d]/g, function(c) {
    return toBaseChar(c, opts);
  })
}

// Example:
console.log(latinify('?eština Ts?hesen?stsestotse Tshiven?a Emigliàn–Rumagnòl Slovenš?ina Português Ti?ng Vi?t Straße'))

// "Cestina Tsehesenestsestotse Tshivenda Emiglian–Rumagnol Slovenscina Portugues Tieng Viet Strasse"


10> 小智..:

我制作了一个Prototype版本:

String.prototype.strip = function() {
  var translate_re = /[öäüÖÄÜß ]/g;
  var translate = {
    "ä":"a", "ö":"o", "ü":"u",
    "Ä":"A", "Ö":"O", "Ü":"U",
    " ":"_", "ß":"ss"   // probably more to come
  };
    return (this.replace(translate_re, function(match){
        return translate[match];})
    );
};

使用如下:

var teststring = 'ä ö ü Ä Ö Ü ß';
teststring.strip();

这会将String更改为a_o_u_A_O_U_ss
