You seem to be confusing "fair" with "equal". Treating everybody the same is not necessarily fair. It seems fair to me to have the most common characters be shortest. I don't have any evidence, but I would guess that Latin characters[1] are used most commonly.

[1] "Latin characters" is the proper term, not "American characters"

thanks! but i just tried to kid which i can't control sometimes.

anyway, i think that even if Latin chars weren't the most used in the world, it would be fair to keep them the primary charset for use in programming and markup languages, as no-one now complains that the international language of medicine is Latin, not, say, Chinese :) as computers started to be massively developed in America.
