There seems to be no possibility to enter Greek characters (like alfa, beta, gamma etc) in it's learning, specifically Test 2.0.

It's very annoying. Use of Greek characters is very common in several subjects, like Physics and Electrical Engineering.

There seems to be a bugs in Test 2.0 as well, if you get your HTML code messed up, you are really in trouble...
Could you please do something with this? As it is now, you have to create a new Test and import all the questions. And even then, you are not really sure if it will work…
