SYNOPSIS
#include <allegro5/allegro.h>
int al_ustr_offset(const ALLEGRO_USTR *us, int index)
DESCRIPTION
Return the offset (in bytes from the start of the string) of the code
point at the specified index in the string. A zero index parameter
will return the first character of the string. If index is negative,
it counts backward from the end of the string, so an index of -1 will
return an offset to the last code point.
If the index is past the end of the string, returns the offset of the
end of the string.
