@Ziad-Mid : 
interesting, thank you!

1. The list formatting was not explicitly supported, so in a sense it works as designed (all numbered items are represented by `{\listtext	0.	}`.  This will likely be a separate enhancement.

2. RTL/LTR attributes are not yet supported by the demo due to many bugs in RTL.

3. Arabic diacritics rendered with the System font look bad, I agree.  Maybe @prrace can weigh on it, looks like changing the font to one of the Arabic ones does improve the rendering, although the result appears not as good compared to Chrome:
