Compensate for XML encoding error in controller
Compensate for XML encoding error in controller

Controller sometimes sent us an invalid XML response. This was due to
the user b'81231297\x16\x16@cuni.cz' who has those ASCII control
characters in their login. "Escape" these control characters to avoid
similar situations.

This is probably not a "correct" fix per se, but I do not have the time
to study XML RFCs to properly escape everything.
