Even simpler idea: if the value will be printed in three basic
representations (decimal, octal and hex), then to see a real character
the user can type somewhere one of these numbers with a C-q prefix
depending on the value of `read-quoted-char-radix'.

BTW, there is one bug with `read-quoted-char-radix':
typing `C-h v read-quoted-char-radix' displays the *Help* buffer
which says that `read-quoted-char-radix' is defined in `custom'.
Typing RET on a reference signals an error:

"Cannot find definition of `read-quoted-char-radix' in library `custom'"

This is because `read-quoted-char-radix' is defined by
`custom-declare-variable-early' which incorrectly associates
it with `custom.el', even though it is defined in `subr.el'.
