 To answer your question about emulated `wchar_t` support, I don't think
 there's much will to support it as this behavior is non-conforming (read:
 adds unnecessary problems) and can be relatively easily fixed with a
 compiler switch. Boost itself is built with the native `wchar_t` enabled,
 and this has been so for many years. Additionally, there are no testers
 with emulated `wchar_t`, so expect breakages.

 With respect to Boost.Log, the emulated `wchar_t` is problematic as it
 makes certain parts of the library behave differently than normal. I added
 a note to the docs stating that. For now I fixed the compilation but in
 the future I may remove support for emulated `wchar_t` completely. I
 highly recommend switching to the native `wchar_t`.
