Is 'þ' in the 256 characters? It has a unicode value of 254 but a UTF-8
numeric value of 195 190. It's literal numeric value (non-UTF-8) is invalid
when treated as UTF-8.

Although the unicode value of 'þ' is less than 256 it still must be
represented with two bytes in UTF-8. This is where it gets confusing to
view UTF-8 as literal. And why I sometimes think it would be nice if UTF-8
was a type unique from literal and unicode.

'þ' acts weird when executed because literal values above 127 are special
and they should never appear in a statement. This would have to be done
differently to allow for international characters in names.
