My customers read Arabic. Can my menu show Arabic names?

Yes. The text you type for a category or a dish is the text customers see, so type the Arabic name, or Arabic and English together in one name. The page's own buttons and labels are in English today. Three of the twelve fonts in the Theme gallery are marked Arabic: Cairo, Almarai and Rubik. Pick one under The look → Storefront font and press Save the look, so Arabic text renders in a font made for it. Changes reach customers on their next page load.
