i post the files in the native .
i post the files in the game main derictory "c/programe files/mount&blade...."
but is still english.
the arabic shown on your picture is not sure. the arabic letter is not separated . the arabic letter write togather like the french minucqile font shown in the picture :
the letters in my picture is togather not like "JACKDAWS LOVE...." . the arabic latters must bee togather
like this "
السلام عليكم . الله كبر . لا الاه الا الله محمد رسول الله"
not like this
"س ا خ م ل ا ل ل ه"
finaly . i think this problem comming from the font.
