Hi @ketul.provakil :wave:

We are actively working to improve all aspects of RTL support, including the Arabic language.
Could you please provide more details about the issue you’re experiencing?


  • Add the interface translation into Serbian (sr-Latn-RS, Serbian (Latin, Serbia and Montenegro)) and Arabic (ar-SA, Arabic - Saudi Arabia)
  • Add RTL support (beta) to the editors UI


  • Fix position of diacritics when typing in Arabic
  • Fix display of highlighting a comment added to RTL text
  • Fix text label for Table of Contents in the RTL UI
  • Fix an issue with shaping text with different direction (RTL and LTR)


  • Added Arabic to all regional settings
  • Improved work of the algorithm for displaying numbers and punctuation in Arabic text for the Neutral and Weak classes
  • Improved fitting for paragraphs with main RTL direction

How do I change interface lang to arabic and enable rtl in documentcument server?

I found it in the documentations.
