Rather than abort, it would be preferable to ignore the bad characters
and keep reading.  Either that or replace them with the unknown
character.  It doesn't look like IOChannel provides a way to recover
from this exception though, other than closing the IOChannel and
giving up.

The choice the programmer has is to catch the exception.  By not
catching it, it looks like glibmm does, and shuts down the IOChannel,
causing the program to hang since it is expecting to get OnReadable
events that never come.  At the very least it should generate an eof
event or something other than just halting in the middle of a read
operation.
