--- Comment #1 from Tomasz Kamiński <tkaminsk at gcc dot gnu.org> ---
We should adjust the signature of parse and format functions to accept
basic_format_parse_context<CharT> and basic_format_context<Out, CharT>
respectively. 
Furthermore we should constrain CharT to char and wchar_t only,
as for other formatters.
