I checked, and I found a bug when using very large fonts. I fixed that now 
(for tomorrows snapshot).

Both work fine for me (after my last fix even at large sizes).

That font is broken. It doesn't support Unicode at least. Try
"ftview -e unic -f 1536 24 hgornata.ttf". This shows you the unicode character 
map of the font starting at U+0600 (the arabic range). You'll see that the 
font does not contain any arabic glyphs in this range.
