libstdc++: Fix Unicode codecvt and add tests [PR86419]
Fixes the conversion from UTF-8 to UTF-16 to properly return partial
instead ok.
Fixes the conversion from UTF-16 to UTF-8 to properly return partial
instead ok.
Fixes the conversion from UTF-8 to UCS-2 to properly return partial
instead error.
Fixes the conversion from UTF-8 to UCS-2 to treat 4-byte UTF-8 sequences
as error just by seeing the leading byte.
Fixes UTF-8 decoding for all codecvts so they detect error at the end of
the input range when the last code point is also incomplete.
