`with-temp-buffer' is not a good option because it may have different
buffer-local environment compared to the actual buffer.
As for `describe-char-display', do you refer to `internal-char-font'?
`internal-char-font' is "For internal use only." though. Or can we get
something out of the `describe-char-display' return value? This function
does not have a docstring, and it is not very clear what the possible
return values can be and which return values are indicative of
non-displayable characters.
