No, paragraphs should not be wrapped in anything. Some systems automatically detect paragraph direction based on its content (basically the first alphabetic letter), but apparently Microsoft systems don't. So you've got to push a button in Word for that.

The gedit text editor from the GNOME project is a good example. Basically anything using latest GNOME libraries implements this. > Best regards, > > Saied > > P.s., My friend Farhad Msoudi who just visited Toronto tells me that the a > huge portion of the CS dept of Toronto university is Iranian. > Congratulations guys!
