a better explanation to the bug is that, the bidi implementation (done
by GTK/Pango as behdad noted) sets the paragraph level to '1' (odd)
which means that this is an arabic line, regardless of the contents.
thats why weak chars (like, / : ( ) ... ) appear as if they were on an
arabic line. at some point (i think) the env var LANG influences the
paragraph level. and that should not be the case.
this is not XCHAT specific i think..

the solution for this problem is that the BIDI implementation needs to
set the paragraph level according to how the Bidi Algorithm says it
should be, which is look for the first strong char, and set accordingly.

a quick look at XCHAT's code or a post to their list, would reveal the
Bidi engine.
