Those lists are quite good examples of why alpha and hex use _different_
algorithms, even ignoring the fact that 'a' has the value '1' and '00' has
the value '0'. With alpha, once you have run out of characters, the first
character is repeated (the symbol for '1', namely 'a'). With hex, two
different characters are used (the symbol for '1' and the symbol for '0').

This is a very important difference.

Ok, thanks.

Cool, that's what I used.

1) has been fixed, thanks to your input. The draft (to be published any
day now) will have lower- and upper-armenian.

2) is Frank Tang's fault. :-) He's the one who implemented many of these
systems in Mozilla, and I used his research as a base for a lot of my
