Re: Need to clarify the effects of bidi paragraph breaks

The bidi reference code published by Unicode comes with a driver that 
implements as "pseudo alphabet". It's not based on case, but a similar 
idea, to give you a way to use familiar letters while you observe the 
results of bidi processing.

http://www.unicode.org/Public/PROGRAMS/BidiReferenceCpp/

On the Unicode site, there's also a small windows program that 
incorporates, among other things, a bidi demo mode 
(http://unicode.org/unibook). It not only shows the results of 
reordering, but also the internal classification of characters. 
Internally it runs the aforementioned bidi reference implementation.
