Add an operator<<(char32_t) to the Stream class, char32_t will be used
as a main character instead of a wchar_t (this is needed on systems
where sizeof(wchar_t) is equal to 2).
while here:
- add to utf8:
size_t wide_to_int(const Stream & stream, size_t stream_index, int & res, bool & correct)
template<typename StreamType, typename OutputFunction> bool wide_to_output_function(StreamType & buffer, OutputFunction output_function, int mode = 1)
template<typename OutputFunction> bool wide_to_output_function_by_index(const Stream & stream, OutputFunction output_function, int mode)
- add to convert/misc:
bool try_esc_to_tex(char32_t c, pt::Stream & out)
bool try_esc_to_html(char32_t c, pt::Stream & out)
