The earliest document I found is N1010
introduced the char16_t and char32_t types along with the conversion
It simply states "Speaking in general, it is desirable to free the C
applications from character-based operations and encourage string-based
operations. The detail of the library for the new character data types
should be left to the future enhancements of the C standard. This
technical report specifies merely the 4 minimum character conversions
among 3 character data types: char, char16_t and char32_t."
