OK, so these are out-of-compose keys like arrows and function keys, and like the
whole keypad on VT2xx/3xx.

Umm, you don't remember the entire ASCII table by heart? Tsk tsk. This is the
kind of thing that everyone should know as most basic, so if anyone wakes you up
in the middle of the night and asks you to recite the ASCII table, you ought to
be able to just recite all 128 characters immediately. (Or at least the 96
characters from space through delete plus the most basic controls, I'll grant
that most of the C0 control characters are not used anywhere and have no real
meaning beyond the paper spec.)

Wait a moment, are you saying that if you enter a code between 80 and 9F through
hex compose while the terminal is set for VT400 mode, 7-bit controls in Setup,
it beeps in error and sends nothing? This is not what the manual says, it says
that it sends the two-byte 7-bit escape sequence equivalent to the C1 control
character entered. So the actual behaviour differs from documentation here,
