Please keep in mind that the job of IETF is to provide protocols, not
policy, and that the semantic issues (such as the risk of confusion
between google.com and G00GLE.com or between google.com and
googlesucks.com) are completely off-topic for the IETF.

I do not see why we should prevent the greek to write names in their
own scripts, with their own rules (such as the final sigma rule).
