If the problem comes and goes as you change fonts, then the problem is
not with Emacs, it is with the fonts you are using: they should
support Arabic shaping.  Emacs by default chooses suitable fonts for
the Arabic script, but if you force Emacs to use certain font, you can
disrupt the automatic font selection algorithm and choose a font that
doesn't support Arabic shaping.

The problems reported earlier existed with any font, and didn't
disappear when a font was changed.
