isValid(
char const** invalidString,
char const* string);Return true if the specified string contains valid UTF-8, and false otherwise. If string contains invalid UTF-8, load into the specified invalidString the address of the beginning of the first invalid UTF-8 sequence encountered; invalidString is unaffected if string contains only valid UTF-8. string is necessarily null-terminated, so it cannot contain embedded null bytes.
