Thank you. I'm glad to hear it.
Are you going to work on others?
If so, there is a point to notice on C-UTF-8.

The motivation to define WCHAR_MAX is that this is necessary to
write C-UTF-8 part of _mbrtowc_r properly. If wchar_t doesn't
have enough size to contain an UCS-4 character, _mbrtowc_r have
to return EILSEQ against a multibyte character larger than 4
bytes in UTF-8 encoding.
