RFC2812 documents ircnet's ircd (only). Compare with RFC1459:
<nick> ::= <letter> { <letter> | <number> | <special> }
<letter> ::= 'a' ... 'z' | 'A' ... 'Z'
<number> ::= '0' ... '9'
<special> ::= '-' | '[' | ']' | '\' | '`' | '^' | '{' | '}'
RFC2812 effectively adds "|" and "_" to <special> and allows most of
<special> as the first character of a nick. Compare with ircu, which
allows "~" anywhere in a nick. Bahamut disallows "~" although a
comment before do_nick_name() says it should be allowed.
>From a strict RFC compliance interpretation, irssi should not allow
"_" in nicknames. From the "be liberal in what you accept" doctrine,
it should allow "_" and "~", since servers allow (and have allowed)
those for a long time.
