I noticed that the code doesn't compile in `c++20` because the type of UTF8
string literals is `char8_t[N]` instead of `char[N]`. This is the error message:
`cannot initialize a parameter of type 'const char *' with an lvalue of type
'const char8_t[21]'`
It compiles if I cast it to the correct type (`__builtin_verbose_trap((const
char *)u8"¡¢£¤¥¦§¨©ª");`).
How important is it to be able to pass UTF8 string literals to the builtin in
c++20 without using any casts?
