good rar/zip archiver that supports moonspeak

I currently use WinRAR, and most of the times I have to change language settings and restart my computer, are just so I can open a japanese-filename archive that WinRAR insists is LOL FUBAR'D. This annoyeth me. So is there a good free archiver that handles both English and Japanese at the same time?

PERMANENTLY SET UR LOCALE TO JAPANESE. U NOOB
