Right-to-left text

I come back to right-to-left text such as Arabic and Hebrew.
(Previous thread was "non-Latin-1 in iCab 3".)

My test page
http://www.unics.uni-hannover.de/nhtcapri/right-to-left.html
lists all HTML and CSS constructs for bidirectional text.
It uses only ASCII digits! You do not need to know Arabic or
Hebrew; you don't even need fonts with Arabic or Hebrew letters.

If your browser passes this test, it is likely to display
Arabic and Hebrew pages correctly.
