Answer 2

如果它不是非常通用的并且你有特殊的字符和短语要替换，你可以将你的特殊字符/短语映射到它们的替换，然后解码字符串并替换它们中的每一个：

var replacements = {
    "créer" : "créer", // this is a phrase
    "Ã" : "é",
    "Â" : "e",
    "©" : ""
};
var url = "http://172.23.113.79/recherche/pages/Results.aspx?k=**cr%c3%83%c2%a9er***";
var decoded = unescape(url); // or decodeURI(url);
for(var key in replacements)
    decoded = decoded.replace(key,replacements[key]);

使它更通用

if (jQuery.browser.msie) {
                retStr = encodeURI(retStr);
            }
