using IRC (Network Open).
I think authorize is ok. working property.
but sometimes it return improperly encoded text .
In my country use multibyte characters typified by East Asia language. reason is that.
Then I have check another irc clients, it seems they send encoding type to server.
Unfortunately, I have no skill for make plugin now ,
so I will need search someone who can code and jägermeister friends.
Anyway Thank you for your reply despite your busy.
