Facebook is now letter page admins post in multiple languages in the same post to cater for different locations that their fans are based in. This isn’t the auto-translate function that currently exists, this is a new feature that allows you to enter multiple versions of text translated in different languages.

Once enabled head back to your page timeline and you will see an option in the ‘Create a post’ box to (Write post in another language) see screenshot below.
