Facebook comments plugin for country specific?

I am new to Facebook API, gone through the diff blogs and Facebook developer and implemented Facebook comments plugin in my site.

I have a question that, do we need to add any thing specific to the country to show the content in their language or Facebook will take care of it开发者_运维百科?

Because my site is available in different countries like Brazil, Spain, and etc..

Thanks, Ranjith

As far as I know, the different Facebook plugins use the local of the logged on user. You don't need to handle this yourself.
