Hello Scott,
I guess that ASCII would be char, UTF-8 would be unsigned char, UTF-16 would
be wchar_t and UTF-32 would be long wchar_t. But it is more appropriate just
to have the three sizes of strings, i.e. 8-bits, 16-bits and 32 bits, and
the ability to have const 16-bit strings.
wchar_t* strchr(wchar_t *string, wchar_t chr){
while(*string != '\0' && *string != chr) ++string;
if(*string == chr) return string;
return NULL;
}
const wchar_t* strchr(const wchar_t *string, wchar_t chr){
while(*string != '\0' && *string != chr) ++string;
if(*string == chr) return string;
return NULL;
}
Cheers,
Dallas.

Do you mean "standardize char as UTF-8, wchar_t as UTF-16, and long
wchar_t as UTF-32"? Because that's not what you said, even if (on
POSIX, but not necessarily C or C++) the sizes would be appropriate.
Implement all the string functions: - strcmp(); mbscmp(); wcscmp(); and
lcscmp().
How exactly do you plan on implementing strchr for UTF-16?
Specifically, what would its signature be?
