Winamp can't load files whose names are in another charset (encoding)
Suppose a system locale charset is in "Western Europe", ie ISO-8859-1 (or the equivalent in Window), Winamp can't read files whose names are, say, in Chinese. Of course, the same happens the other way: if a system is in Big5 (Traditional Chinese), and if I want to play a French song whose filename contains accented characters, eg "PrÃ¨s de moi", Winamp can't read it.
AFAIK, since Win98, win filesystem is based on Unicode. I use Win2000 at home which is also a Unicode based system. (WinNT4 is Unicode based too but I don't know how many people use WinNT at home.) On the other hand, Joliet CDRom format supports Unicode by default too. So if Winamp requests filename in Unicode from Windows, it should be able to read every file without having to care about every existing encoding in the world.
BTW, any plan to support Unicode in tag?
