I've found this useful link https://www.blm.gov/sites/blm.gov/fi...k_H-1297-1.pdf although dated 2015. We all know how fast-paced developments in accessibility are, but this is a practical guide to develop accessible content.
I was actually seeking info on accessibility in Arabic and found these couple of good tips:
- As for any other language, KISS is the word! It translates in this tip: We suggest limiting your document to no more than two fonts.
- Fonts specifically recommended for Arabic, at least for MS Word content are: Arabic typesetting, Traditional Arabic and Simplified Arabic.
- A font known to have issues for Arabic, and therefore not recommended at all is the Adobe Arabic.
