Unfortunately, the IRC protocol has no standard support for
internationalization. The protocol was not designed to support
explicit negotiation of character sets between users, by channel, or
by server/network, and it was not designed with a way to add such
support as an authoritative extension (however, see below).

Traditionally, all messages sent through IRC are assumed to be using a
modified form of US-ASCII (possibly refered to as the "ascii character
set" with "rfc1459 case mappings"), and it may be a feature that all
messages received by IRC clients are displayed in that character set
rather than their host session's character set (unless explicitly
reconfigured by the user).

An alternative, where the IRC client presumes that all incoming
messages are in the character set of its host session, does not sound
more reasonable than the traditional behaviour.

Another alternative may be available on servers that use the
non-standard 005 "extended version" numeric sent during connect. This
numeric exists on many major IRC servers and includes both "CHARSET"
and "CASEMAPPING" fields, which could be used to tell the client which
character set and case map to use by default (instead of US-ASCII and
the pseudo-Scandinavian "rfc1459" case map). This would be
per-network, however, as it would not be reasonable to have some
servers on a network advertize one character set and other servers
advertize a different one, so it would only make sense for
pure-Japanese IRC networks (it could not be used by a Japanese user
using the Red Hat IRC network, the EFnet IRC network, etc.).

The relevant documentation is RFC 1459 "Internet Relay Chat Protocol"
section 2.2 "Character codes", which specifically states that no
thought was given to character code specification in the protocol.
