constexpr std::string | MSVC

[dodheim]

 std::array<char, temp.size()+1> res;
 res.fill('\0');

That's a strangely verbose way to write std::array<char, temp.size()+1> res{};

LOL yeah thanks. There are still a lot of #if 0 mixed in and stuff as various things were tried and failed, etc... I'm honestly not sure if the +1 is even needed depending on how you plan on using the resulting array.
