Thank you for testing my code.

That's perhaps because they define those glyphs for ZWNJ.

To avoid that problem, there are two ways:
(1) display ZWNJ with a glyph for space (if the font has a glyph for space)
(2) do not generate a glypgh for ZWNJ

Please try the attached new version.  It tries (1).  If you change the
value of arabic-font-shape-gstring to
`arabic-font-shape-gstring-ZWNJ-absorb, it tries (2).

As an editor, I think (1) is better, but an Arabic/Persian user may have
different opinion.
