I don't think this is right, or shouldn't be right, anyway.. Surely it
stands for a character. Unicode codepoints include non-characters such
as the surrogate codepoints used by UTF-16 to map non-BMP codepoints to
pairs of 16-bit codepoints. 

I don't think you ought to be able to see a surrogate codepoint as a Char.
