Обоснование (Rationale)
This function is aligned with the ISO/IEC 9899:1999 standard, and
in doing so a few ``obvious'' things were not included.
Specifically, the set of characters allowed in a scanset is
limited to single-byte characters. In other similar places,
multi-byte characters have been permitted, but for alignment with
the ISO/IEC 9899:1999 standard, it has not been done here.
Applications needing this could use the corresponding wide-
character functions to achieve the desired results.
