Yes, there aren't yet any I/O functions defined for char8_t and therefore
that's the best we can do right now. I have all kinds of ugly macros to
high these casts.

locale and then uses u8"" strings internally. This causes warnings with
-Wformat.

int main()
{
printf((const char*) u8"test %d\n", 1);
return 0;
}
Compile with
g++ -std=gnu++20 -c -O -Wall t.cc
and you'll
