We launched another round of 6 languages in .BIZ on January 16th, 2008: Finnish, Hungarian, Latvian, Lithuanian, Polish and Portuguese (press release).
While NeuStar already has many Latin-based IDN languages in its portfolio, one may wonder why we would bother making the Venn diagram so complicated. Just define a Latin script-based table and be done with it! Well, since we tend to take a more conservative approach with IDN, it is safer to have each language table contain only the characters used by that language proper and nothing else1. After all, we’re here to provide value and not to make a quick buck (at least that’s how I see it.)
1 Language is constantly evolving. Often, it is not easy trying to determine if a character used in borrowed words is well-assimilated in the culture to be considered part of the language. There are no clear rules, do we follow the guidelines from the trademark offices’ of the countries in which the language is used? Or do we follow the ccTLD registry (if we do, does it make sense for a gTLD?) Or language institutions? Thankfully, there are many great resources to draw from.
