刪除變音符號不工作

我發現來自Apache的這個代碼刪除變音符號，但它不爲我工作（儘管它似乎對其他大多數人的工作）刪除變音符號不工作

我在這裏錯過了什麼？

Apache解決方案適用於單個代碼序列，其中例如，\ u00D1由Ñ表示。但是，也可以使用兩個字符：N（\ u004E）和組合代字符（\ u0303）來創建一個Ñ，就像在字符串中一樣。

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

被定義爲規範等價代碼點序列假設爲具有相同的外觀和含義印刷或顯示時。例如，代碼點U + 006E（拉丁語小寫「n」）後跟U + 0303（組合代字符「◌」）由定義，Unicode與單個代碼點U + 00F1 （西班牙字母的小寫字母「ñ」）。

一個天真的解決方案將是一個空字符串的映射添加到組合變音符號：

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; 
    }); 
}

會不會有另一種解決方案覆蓋這個？在這裏列表： http://stackoverflow.com/questions/990904/remove-accents-diacritics-in-a-string-in-javascript 而沒有任何工作 –

添加一種可能的方式來刪除組合變音符號。 –

刪除變音符號不工作
