Earlier, MRAB suggested that unicodedata.name() could return the U+ code point in the case of unnamed characters. I think it would be better to have a separate unicodedata function to return the code point, and leave the current behaviour of name() alone.

def codepoint(c):
     return 'U+{:04X}'.format(ord(c))

This should always succeed for any character.
