Actually no.

It can overlap. But a codeunit is NOT a character.

For example a codeunit that holds a codepoint of class "combining mark", 
this is not a character. It is just something that can form a character 
if combined with other codepoints.

Also not a character. Same as above.

Some Codepoints happen to also be a character. But some are not.
