Comment 4 for bug 1823543

@Jon, I looked into the wchar_t vs char compiler flag, and I really don't think it's going to cause a lot of bugs like @Wayne worries. The only downside appears to be more storage for strings, but it's not like we're a word-processor with tons of text (and besides, even then text is tiny next to bitmaps).

Anyway, I think it's worth trying at least locally. If it works we could rip out many of the mutex hacks....
