(is_high_surrogate, is_low_surrogate, surrogate_pair_to_code_point): Define convenience functions. (read_utf8_code_point): Return relevant constant to distinguish incomplete characters from invalid sequences. (read_utf16_code_point): Likewise. Check for invalid sequences. (ucs4_in, utf16_in): Use incomplete_mb_character constant. (utf16_out): Check for invalid sequences. (utf16_span): Fix condition. (ucs2_out): Use is_high_surrogate. (ucs2_in): Use incomplete_mb_character constant and fix condition. * testsuite/22_locale/codecvt/char16_t.cc: Fix whitespace. * testsuite/22_locale/conversions/buffer/1.cc: New. * testsuite/22_locale/conversions/string/2.cc: Use char16_t and char32_t instead of wchar_t. * testsuite/22_locale/conversions/string/3.cc: New.
