Subject: Ignore all control characters not handled Taken from vt100 programmer
manual:
Control characters have values of \000 - \037, and \177. The control
characters recognized by the VT100 are shown in Table 3-10. All
other control codes cause no action to be taken.
We have to take attention when we are using alternate charset, because in
this cases they are not used as control characters.
