Arabic character in osso-xterm
 

Hi, I have a problem with Arabic character in Osso-xterm, the characters are separated within the word ( check out the screenshot). May be the problem with the encoding? What to do to solve it?

They should be shown as
بسم الله الرحمن الرحين
not
م ي ح رل ا ن م ح ر ل ا م س ب

thanks
