A non-confusing solution to the issue “I have a code point and I’d
like to know which character that is, but I don’t want Emacs to spend
time trying all fonts to see if any of them has a glyph” could be to
show the Unicode name for code points greater than
eval-expression-print-maximum-character and less than (max-char).
