First of all they are foundamentally broken. As our convention is that std::string is always UTF-8, these functions assume that the multi-byte character version of TString (std::string) from windows is also in UTF-8, which is almost always wrong. We are not going to build multi-byte character build, and even if we do, this dirty work should be handled by frontend framework early.
We always use unicode internally. Any dirty work of conversion with other codec should be handled by frontend framework (Qt). Further more, ShiftJIS/CP1252 are not special (they are not code set used by 3ds, or any guest/host dependencies we have), so there is no reason to specifically include them
We can just use the variant of std::string's replace() function that can
replace an occurrence with N copies of the same character, eliminating
the need to allocate a std::string containing a buffer of spaces.
Add a new set of logging macros based on fmtlib
Similar but not exactly the same as https://github.com/citra-emu/citra/pull/3533
Citra currently uses a different version of fmt, which does not support FMT_VARIADIC so
make_args is used instead. On the other hand, yuzu uses fmt 4.1.0 which doesn't have make_args yet
so FMT_VARIADIC is used.
