In OmegaWiki you can have many of the labels used in the data part in your language as well. For this to function, you have to select a language in the "user preferences" and there have to be translations of the words involved. Words like Estonian, Georgian or noun, verb, adjective will be shown in the selected language.
As the user interface is one of the most critical aspects for getting buy-in, it is something I often spend time on. Given that I do not speak languages like tiếng Việt, it is not always easy to find the right translations. For this language I was not able to find Gujarati. More bewildering was that I could not initially find the word Korean, it was there as korean with "tiếng Triều tiên" as its translation.
All in all I have added more than 10 translations in this latest session. I am sure that people who speak this language will have an easier time doing the same job.
