    _______________________________________________________

Details:

As far as I can tell, Octave's parser currently handles octal escape sequences
in double-quoted strings but not hexadecimal escape sequences. It would be
desirable to handle both to be consistent with C/Perl/Python/etc and to be
consistent with escape sequences handled by printf/fprintf/sprintf (see also
bug #39774).

Also the Octave manual describes the NUL byte as the only valid octal escape
sequence in the section on escape sequences "doc escape", but in fact any
octal constant works currently.

Would this added feature break compatibility or not be desirable for any
reason?
