Work around incorrect wchar_t text serialization

`std::char_traits<wchar_t>::length()` would return the wrong length for
a wide string under Wine, and thus also for `String128`. This would
cause parts of the strings to get cut off. As a workaround we'll just
serialize the entire container including all null bytes at the end.
