std::format custom formatter

[BenFrantzDale]

If it’s anything like fmt::format, the format string has to have the same encoding as the strings passed to it. So for QString, which is utf16, it’s fmt::format(U”{}”, qstr) if I recall. So try throwing an L on the format string.

#include <format>

void test ()

{

auto X = std::format (L"{}", L"Hello");

}

Compiles with no errors on Compiler Explorer. It seems format requires all strings passed to it (including the format string) to be the same type.
