seems like raylib doesn't support arabic and rtl

I'm afraid raylib does not support RTL (right-to-left) text at the moment and neither complex ligatures, a library like Harfbuzz is recommended.

manually reshaping the app_ar.po file and flipping text seems decent as done with the circled text

Is it just on the left, or is the text actually flipped?

From the original photo..

• the text is flipped, so a simple shift to the right wont do it
• the letters are being drawn as isolated characters instead of the correct joined forms

The second photo shows what it looks like after manually fixing it - the characters are (mostly) using the proper joined forms, and only the circled text is flipped back to the correct RTL order. It would then also require the text to be right aligned.
