What makes you think that?  As far as Emacs is concerned, a character
is a character.  For example, in bidi text you might want (in theory
-- in practice it's usually a bad idea) to insert a directional marker
character.  In Japanese or Chinese where the normal practice is to
break on any word component, you might want to use a word joiner
character to save English words from the kinsoku scalpel.
