stty sane isn't supposed to do anything "sane" to the terminal, I think, 
just to the tty device.
The tool to use would be 'reset'. So I'll try to find out why 'reset' 
doesn't reset the character set :-\ .

There are two methods to switch to the alternate character set. One is 
by just sending a Control-N. Most terminals "guard" this method by 
requiring an enable sequence before this works. I guess this would 
considerably reduce the risk that this happens, that's probably why they 
do it.
I didn't implement the guarding mechanism in fhandler_console (although 
I prepared it somewhat) so I think I should fully implement that.
Also I tuned mined to send the corresponding disable sequence on exit 
which it didn't, probably (and weird enough) because terminfo maintains 
the enable capability but no disable capability...

See above; I don't think it's supposed to do that.

Is it sufficient to complete this in 2 weeks (after Easter time)?
