I can't talk in channels whose name is composed of multibyte 
character(at least japansese). We cannot create such multibyte channel
in freenode, but can do it in Japan WIDE IRC Network ircd.

When I send privmsg in such channel, I got Error message
 "Error: #???? No Such nick or channel.", #???? is channel name 
which is garbled...

- How Reproducible.
Always

- Reproduce steps: 

1. Run Konvi, and Press "F2".
2. On Server List, Press "New".
3. Specify server "irc.nara.wide.ad.jp" which is ircd in Japan WIDE Network.
4. Press Identity "Edit" Button.
5. In Detail Tab, Specify Encoding "Japanese(iso-2022-jp)".
 (euc_jp, jis7, sjis is also ok)
6. Connect to the server. 
7. Join channel whose name is composed of multibyte character,
for example "/join #テスト" (which means "/join #test" in English)
8. send privmsg to it, for example "/privmsg #test test"

- expected result:

i can see "test" in message view.

- actual result:

I got error. "Error: #???? No Such nick or channel.",
#???? is garbled ...
