I have noticed quite a few discussion threads in the Articulate community forums asking about how to include non-Roman character sets in courses. You can insert text that uses many different character sets in PowerPoint; however, when the presentation is published with Articulate, the text does not publish correctly.
I noticed a recent forum post in which the instructional designer pointed out that Quizmaker allowed him to create a course in Chinese, so I thought I would test other languages to see how Quizmaker works. Very well, as it turns out. I recorded a demonstration using Screenr to show what it looks like.
So if you are creating courses in languages that use different character sets, Quizmaker may be an option--at least until Articulate adds support for other character sets right in Presenter.
