Accents in URL, how can I escape them correctly ?

I have to get what is next to the # character in the URL (in javascript). When there's an é, for example, 开发者_开发技巧I get escaped characters. I can unescape() them, but I get weird characters such as Ã. How can I get the right characters ?

use encodeURIComponent and decodeURIComponent. escape and unescape will be useful only for ASCII charset, while the former supports unicode charsets.
