Theming for specific language

Is there a way to automatically wrap all "translated" text with html tags? For example, the font for dz (Dzongkha/Tibetan) is really quite small compared to western fonts due to the possible height of characters in the language. It would be very useful to take any text and wrap it with tags so that I could then institute text formatting with a stylesheet, while not disturbing and western text that may be untranslated.
