爲什麼這個greasemonkey代碼不能使用UTF8字符？

Question

我想在Twitter上使用這個greasemonkey腳本。當我點擊「RT」時，如果它是英文的，它會正確地捕獲引用的文本，但不會像日文等其他語言。這怎麼解決？

Answer 1

該代碼故意刪除非ASCII字符。

問題是ytrim函數。 不要這樣寫代碼！（分配內if()，過度在線等）

替換ytrim有：

function ytrim (s) { 
    var str  = s.toString().trim(); 
    if (! str) { 
     return str; 
    } 
    var lines = str.replace (/^\s+|\s+$/g, '').split (/\s*\n\s*/); 
    str   = lines.join (' ').replace (/[\s]{2,}/, ' '); 
    return str; 
} 

，這將緩解這個問題的全部或部分。
