So, it seems like this broke one of `basic_arg_format`'s private constructors.. Sorry for that.
explicit basic_format_arg(_Tp __v) noexcept
requires(same_as<_Tp, char_type> ||
(same_as<_Tp, char> && same_as<char_type, wchar_t>)) [....]
explicit basic_format_arg(const _Tp& __v) [...]
This is now ambiguous when calling `basic_format_arg(char)` because the argument type is different and comparing constraints is not allowed. @Mordante could you maybe take a look? I've reverted in the meantime.
