[Wine] Invalid characters when dealing with Japanese language

[GameKyuubi]

So I'm running uTorrent through Wine and it works for just about every download, but some downloads, particularly ones with files with Japanese characters in them, screw things up.  uTorrent reports "Error: Invalid Name" in the status of the torrent, and I noticed that the files being downloaded have been replaced with a bunch of question marks where Japanese characters should be.  I try it with Ktorrent and it works fine, Japanese characters and everything.  Is there a fix for this?  Thanks.
