You would be having customers all around the world and our help desk does support a global reach to customers in their respective languages. This feature that aids this is called "Multilingual Support" which is available from our garden plan. 

Please navigate to Admin -> Account -> Helpdesk Settings where you would see an option called "Manage Languages" which would allow you to add supported languages. When you click on manage languages, you would see an eye option which when clicked upon would be visible on the portal. By default, they are hidden. 

Freshdesk has 30+ languages for multilingual support. There is no limit on the number of languages for each account.
