Use `__unicode::__field_width` to compute the estimated witdh of the charcter for unicode wide encoding. PR libstdc++/119593 libstdc++-v3/ChangeLog: * include/bits/unicode.h (__unicode::__literal_encoding_is_unicode<_CharT>): Corrected handing for UTF-16 and UTF-32 with "LE" or "BE" suffix. * include/std/format (__formatter_str::_S_character_width): Define. (__formatter_str::_S_character_width): Updated passed char length. * testsuite/std/format/functions/format.cc: Test for wchar_t.
