At Loc.Pro, we do not deal with all the languages but only with the ones we know best. At the moment, we have three “target” languages in our portfolio: Turkish, Arabic and Greek. We only work with the native linguists in these languages. The source languages we offer our services are English, German, French, Spanish and Russian for now.
You can find detailed information for Turkish here and Arabic here, including the parts of the World they are spoken, interesting facts and statistics, and challenges about translation and localization.
