laura sorry for lating. it's new year in iran and i had some busy days but now i have a lot
of free time.
and yes laura dear. they have a same sound but someones like write "j" in this mode "zh"
i thought it's better that you know both mode in pinglish(writing persian words by english font)
anyway we write (ج ) by this font (j) also.
( ژ ) has a sound like "je" in french and (ج) has a sound such as "just" in english...
if you still have a problem plz say. i'll try explain better.
