Wait nevermind I forgot how unicode works. This means codepoints 128-255 are printed as bytes if the integer they are in is <=8 bits, but as codepoints if >8 bits which is strange and inconsistent. |

#5564. This allows integers <= u21 to be printed as unicode codepoints. I'm not sure what should be done for the error conditions when a codepoint is invalid.
