[Wine] How to make UNICODE characters to display correctly?

[Yuri]

I run WBridge5 (French version) under wine-1.1.1 on FreeBSD-7.0.
It runs ok except for every UNICODE character is replaced by the little box.
Also in some message boxes symbols that obviously should be some French 
characters that aren't part of normal Latin alphabet are replaced with 
Chinese characters.

How to make UNICODE to display correctly?

Thank you,
Yuri
