now included the same way as utf8, though i'm not sure if it really works but at least it should partially :) Input line is now internally using 32bit chars but it's converted to 8bit chars for external use. Text buffer supports only 8bit + utf8 for now. git-svn-id: http://svn.irssi.org/repos/irssi/trunk@2448 dbcabf3a-b0e7-0310-adc4-f8d773084564
