Anyway, Arabic strings are examples of exponential explosions with large coefficients a lot easier to understand for most of you than Chinese ones.
the density of variant (context dependent) characters in arabic script, whether sampled as text, or sampled as domain names, is sparse, relative to the density of "variant" characters in the (unified) han script(s), which is not quite 2^^n, where n is the number of characters in a label, but is sufficiently close to allow the "exponential" term to be reasonably used.
i know this to be the case, but just in case the point was not appreciated by the icann*, and other ietf persons present** at the idn session during the icann brussels meeting, i carefully asked the density question of the presenters, one a han script (chinese) domain name registry operator, the other an arabic script (arabic) domain name registry operator. their answers were as i expected, and fail to support a "Arabic strings are examples of exponential explosions with large coefficients" claim.
variants in arabic script present problems to the idn(a) specification(s) that assume "unicode" as the character repertoire, but they are unlike in scale the problems presented sc/tc equivalence classes presented with similar conditions and assumptions.
