I am not an expert in our IMM or multi-language code, but from looking at the code there's no good way to handle the error from this place. I'd be curious why MultiByteToWideChar fails. My guess would be that the multi-byte string contains characters that are not valid in the selected language, and that XIM and Wine disagree on the validity of the input.

Can you provide the language where this problem happens and what the input string passed to MultiByteToWideChar in this case is?
