Unfortunately, this is not directly possible.
Alt/Meta key combinations have no representation in ASCII or UTF-8.
Instead, they are generated as events by the runtime system, where key
events may have certain bits set for modifier keys.
As such, they are very system-dependent. External libraries like
'termcap/terminfo' or 'curses' can be used to handle them.
BTW, this is one of the reasons why the PicoLisp line editor uses a
'vi'-style user interface. It needs only ASCII-keys.
