Char type was converted to wchar_t and then was serialized as utf-8 stream. Let char type will always be one char, of course it need to be a valid utf-8 sequence. Let FT::dont_use_utf8 apply only to wchar_t and std::wstring but ignore it if FT::hexadecimal or FT::binary are defined. Now we have bool BaseExpression::esc_char(wchar_t val, pt::TextStream & stream) method which (in most cases) will be used in derived classes. Let wchar_t (and std::wstring) will be stored as 8 hex digits when using FT::hexadecimal or FT::binary (and ignore FT::dont_use_utf8 in such a case).
