Yup, I confirm both ;-)

Confirmed.

Fixed... thanks to a hint from behdad...

Not sure what mirroring means here. 

mirroring mostly applies to characters like '(', ')', '<', '>'...
check the CapRTL screenshot... no mirroring there..

Yup, saw some oddities with regard to parentheses.

Fixed...

I also saw some oddities with regard to line breaks (if you have a long
text line - the break doesn't happen where one would expect - no biggie).
In ar_utf8, less the file and note the very last line to see what I mean.
This is most definitely NOT a priority.

havent tried that yet...

Ahmad, you had noted that putyy will be 80 characters wide max - that is
not necessarily true and so you should not always consider that to be the
norm (I was running it as 115x25 for instance :-).


i meant on average... i meant that its hard to exceed the 61 explicit
levels limit on a line that averages at 80 chars...


anyway, ScreenShots available here, (thanks to Osax) :))

the first, putty1 is putty using CapRTL character set...
you can compare it to these results...

the second, putty2 is doing shaping and using latin
and arabic charactersets for Bidi...

btw, mirroring is not yet implemented...

ak.
