The function does not have the purpose of showing key codes. It is
really only to turn a string into something without non-printable
characters. That's it.
The byte sequences used for a special character may also appear in a
file or in a file name, they must not be interpreted as a special key
then.
If you really want to convert a byte sequence to special key names
another function would need to be used.
