But that doesn't work for non-ascii characters. Hence my previous question 
about the relative importance of "e" vs "é" for ex.

If we have a function like (char-after) that is defined as "Return(ing) 
character in current buffer at position POS." then it should do that for all 
the characters defined in the emacs supported character set, shouldn't it?

I'm fine with integers evaluation displaying only number values by the way. But 
maybe (char-after) and similar functions should use a different value for
