Description
I copy pasted to someone a line from gnome-terminal that contained characters below 0x32 character values and sent it off with empathy. After that I got disconnected from my jabber server immediately and the message didn't go through.
The line tries was basically
./appname: line 1: <0x7F>ELF<0x02>``<0x01>``<0x01>``<0x02>: not found
Where <0xnn> was the actual character (rendered with 00nn in a box by pango).
on #telepathy people told that these characters shouldn't be allowed to be sent at all and Send() should reject it or filter them out or replace with something.
For example:
<smcv> (reject / replace with <0xfoo> / replace with spaces / delete would seem to be the vaguely sane possibilities)
It might be useful for there to be a way for advanced client applications to know something was done, to report it for the user.
