Since python-arabic-reshaper GitHub - mpcabd/python-arabic-reshaper: Reconstruct Arabic sentences to be used in applications that don't support Arabic is available by pip install, we should probably be bundling it with PsychoPy and potentially integrating some functions into our text stimuli.
But the current PsychoPy developers struggle with this, as we aren’t familiar with Arabic/Farsi/Urdu text. For example, I just ran the examples in the README at GitHub - mpcabd/python-arabic-reshaper: Reconstruct Arabic sentences to be used in applications that don't support Arabic and I can’t see what the difference is before and after the transformation (the example text doesn’t seem to match the bitmaps). We really need someone to help us with testing and implementing this.
I put out a request for this last year but the silence was deafening:
I think @jon has included the python-bidi package with PsychoPy for quite some time, so that is already available to you at least.
