ALLEGRO_USTR *al_ustr_dup_substr(const ALLEGRO_USTR *us, int start_pos,
   int end_pos)

Return a new copy of a string, containing its contents in the byte interval [start_pos, end_pos). The new string will be NUL terminated and will need to be freed with al_ustr_free(3).

If necessary, use al_ustr_offset(3) to find the byte offsets for a given code point that you are interested in.
