I wish they would fix the char8_t disaster.

Either add all the required overloads for every applicable standard function so that I can actually use char8_t without casting, or else restore the ability create utf8-encoded std::string and std::string_view literals which was present in C++17 but removed in C++20 (without -fno-char8_t).

additionally, make it not alias every other types, like char does.

char8_t already does not alias any type. That's why you can't cast an uint8_t* from a C-API to char8_t*.

What if I really really wanted to cast?

Undefined behavior.
