It is, but I don't know of any practical way of eliminating that
inconsistency. In the normal case, where the current
file-name-coding-system is the same as the ANSI codepage, there is no
inconsistency, so using CharNextExA/CharPrevExA is never worse than
using _mbsinc/_mbsdec. It is sometimes better, because the code which
calls the _mbs* functions is executed only by some functions in w32.c.
> _mbsinc/_mbsdec would simply be sufficient?
That would preclude code like this:
(let ((file-name-coding-system 'cp932))
(expand-file-name "SOMETHING" "C:/")
I think it's reasonable to expect this to be supported, even if the
default file-name encoding is not cp932.

The intended behavior is to downcase letters for which lower-case is
defined. I don't know if this is limited to Latin characters.
