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 eval-expression-print-maximum-character.


>> Also, eval-expression-print-maximum-character is described in "24.9 Evaluating Emacs Lisp Expressions" but unlike eval-expression-print-length and eval-expression-print-level it is not indexed in the elisp reference even though both are also described only in that same chapter. Is that an oversight ?

Ok, I see, Thank you. Is there a general policy to just mention/define variables and not give default values in the manual ?
