From #4978 (comment):

heads up that Docsy (and hence this repo) doesn't fully support RTL languages yet. I'm working on it, but the feature might not land for a few weeks or months -- though I do see it happening before the end of the year. Reference: google/docsy#1442.

We have made progress on Docsy support for RTL languages.

@Metal-Bat - could you take a look at https://example.docsy.dev/fa/docs/ and let us know if there are any layout problems. (We know about the [i18n] tags not yet being defined, those will be addressed via google/docsy#2019).

If you find any issues, please add a note to google/docsy#1442. Thanks!
