Less and less fonts displayed correctly on Android

I did some comprehensive testing on various Android Versions regarding Asian/Arabic Fonts.

It seems that less and less fonts are displayed correctly towards the newer Android Versions. I made tests for spark label, textarea and button. You can see the results here:

I marked with green and red, correct and wrong display of the text. The problem with Arabic is the text direction.

Below is the code used. Compiled with Flex 4.11 and Air 3.9. I played around with a few other SDK versions but basically with same result.

I think this needs urgent attention, especially as more and more updates for Android 4.3 and 4.4 will come out soon.

I will post the same at the Apache Flex forums as I am not sure who is responsible for fixing this.
