     `utf16_len` count (in characters) gives the length of `utf16`. If `utf16`
     is NUL terminated, `utf16_len` can be set to -1, otherwise it must be
     specified. If `wtf8_ptr` is `NULL`, no result will be computed, but the

     If `*wtf8_ptr` is `NULL`, space for the conversion will be allocated and

     Otherwise, the length of `*wtf8_ptr` must be passed in `wtf8_len_ptr`. The
