Is it specific to French keyboards ? In fact, this bug shows that wine currently doesn't use the XKB extension when available to find and check keysyms and keycodes. It affects all keyboards using at least AltGr modifier.
If you read wine-devel, you know that I've sent a patch which is still waiting comments.
