Re: [alreq] Are all numbers equal?

http://unicode.org/reports/tr9/#AN
Section : 3.2 Bidirectional Character Types
"[...]
* As of Unicode 4.0, the Bidirectional Character Types of a few Indic 
characters were altered so that the Bidirectional Algorithm preserves 
canonical equivalence. That is, two canonically equivalent strings 
will result in equivalent ordering after applying the algorithm."

I guess the "few Indic characters" are the Eastern Arabic-Indic digits
 in range U+06F0..U+06F9, which are classified "European Number" vs 
"Arabic numbers". 
I wonder what is the "canonical equivalence" problem in question. 
Didn't find more details.
