Well, IRC channels begin with the # character. For example, to join the
channel #debian on irc.debian.org via the IRC gateway at irc.jabber.org,
you would type the following as a groupchat room in your Jabber client:
#debian%irc.debian.org at irc.jabber.org
So if you were accustomed to joining a channel called #40;daysand40nights
on irc.alladin.lit via irc.jabber.org, then it is within the realm of
possibility that you might try to join that channel but actually be
directed to some other channel, namely:
@daysand40nights%irc.alladin.lit at irc.example.com.
However, I see this as much less likely than problems with MSN gateways
because (1) very few people have ever used one of the IRC gateways (2)
very few IRC channels begin with #xx; and (3) very few Jabber users ever
put groupchat rooms in their rosters.

So \40 for @ (etc.)?
