@rezaaa this is a good idea, but the font should probably be applied to all calendars that use an Arabic script (including the playground as well). In other words, it should depend on selecting a locale that uses an Arabic script.

@gpbl That makes sense 👍 I agree it should be tied to the locale rather than applied manually.
I look into it.

@gpbl Applied font globally to all RTL (right-to-left) components across the examples app, and shadow DOM components.
