Hi,

Currently, ‘erc-notifications-notify’ signals an error if the message
contains invalid XML characters.  These characters can be either either
IRC control codes (e.g., ^B for bold text or ^C6,12 for colored text) or
just plain invalid data.

This patch changes the behavior so that they are stripped instead.  To
test, try sending yourself a message such as

   /msg <nick> ^BHi!

where <nick> is your own nick.  The current version will signal an error
whereas this patch won’t.

The proposed patch is attached to this message.
