Good point, I don't think about that before, but $mid doesn't support .props (it's the same for other identifiers like $asc, $chr etc...), so if the text isn't a props (event invalid), mirc should return the text as a "plain text" :

Code:
//echo -a $chan(#channelname).topic2 < return channel name
//echo -a $chan(#channelname).topic  < return the topic of the channel
//echo -a $chan(#channelname)text    < imo, should return $chan(#channelname)text
