Sorry to be a nuisance, but while I was away I thought of two other points:

1. IDNs allow any unicode character, not necessary just letters, AFAIK; e.g. `☃.net` Although I don't know if that counts as a "letter" or not, but I think for the purpose, what you've specified is enough

2. More importantly, you haven't accounted for IDN ccTLDs, e.g. `www.test.рф`! :)
