We can always modify the standard so that we get strong types via
compiler magic. I was thinking:

utf8'a' -> std::unicode::utf8_code_unit
utf16'a' -> std::unicode::utf16_code_unit
utf32'a' -> std::unicode::utf32_code_unit
utf8"a" -> std::unicode::utf8_code_unit_sequence_view
utf16"a" -> std::unicode::utf16_code_unit_sequence_view
utf32"a" -> std::unicode::utf32_code_unit_sequence_view

Well, that's future. I want something I can use now.

Also, does the standard require well formed sequences in literals?
