删除变音符号不工作

我发现来自Apache的这个代码删除变音符号，但它不为我工作（尽管它似乎对其他大多数人的工作）删除变音符号不工作

Apache解决方案适用于单个代码序列，其中例如，\ u00D1由Ñ表示。但是，也可以使用两个字符：N（\ u004E）和组合代字符（\ u0303）来创建一个Ñ，就像在字符串中一样。

维基百科： https://en.wikipedia.org/wiki/Unicode_equivalence

被定义为规范等价代码点序列假设为具有相同的外观和含义印刷或显示时。例如，代码点U + 006E（拉丁语小写 “n”）后跟U + 0303（组合代字符“◌”）由定义，Unicode与单个代码点U + 00F1 （西班牙字母的小写字母“ñ”）。

一个天真的解决方案将是一个空字符串的映射添加到组合变音符号：

var defaultDiacriticsRemovalMap = [ 
    {'base':'','letters':'\u0300\u0301\u0302\u0303\u0304\u0305\u0306\u0307\u0308\u0309\u030a'}, // etc. up to \u036f 
... 
]

更新_removeDiacritics以及

function _removeDiacritics (str) { 
    return str.replace(/[^\u0000-\u007E]/g, function(a){ 
     var mappedChar = diacriticsMap[a]; 
     return mappedChar !== undefined ? mappedChar : a; 
    }); 
}

会不会有另一种解决方案覆盖这个？在这里列表： http://stackoverflow.com/questions/990904/remove-accents-diacritics-in-a-string-in-javascript 而没有任何工作 –

添加一种可能的方式来删除组合变音符号。 –
