- add the convertion between yycc_char8_t and system char type because we decide use our char8_t in the whole library. - make a clear boundary between yycc char8_t declarations and related assist functions. the declarations present in internal header and assist functions are written in encoding helper. - use std::basic_string_view instead of std::basic_string to provide more abilities to encoding convertion functions and reduce the redundant memory occupation at the same time.
