I think the Simp and Trad Chinese only differs in letters, they have no difference in grammar. Too bad I don't know anything in coding but if there is a word file I can help to translate too.
For native speaker(like me lol), the differences between Simp and trad. are not only letters, but also the structure of the sentence and the vocabularies. I would say, the "Chinese" in Hong Kong (ya, that former British colony and the place whom refused to hand out Snowden, and where I live), China and Taiwan are so different that, everyone could easily figure out where you come from by listen to what you speak or what you write or how you construct your sentences.
Though Taiwan and Hong Kong both use the Trad Chinese, still the Taiwanese and HongKongers could not understand easily what the HongKongers/Taiwanese are writing about......
Well, for Foreigner, I guess it is too harsh to require them understanding these differences......
