Collabora Online 21.11 now supports right-to-left (RTL) text input within all modules. This makes it easier to create and edit documents in Persian or Arabic. The text direction can be set in the “Format” tab under the option “Page Style” (or “Slide Style” for presentations). The code in Collabora Online can detect several RTL language settings and will mirror the user interface accordingly.
