ENS Name Normalization

@raffy

The difference is that you have to first identify and separate the emoji from IDNA processing. The text parts go through IDNA and the emoji parts are as-is (or could be passed through a new algorithm for Emoji.)

Thanks for the summary!

@raffy

This let’s you enable IDNA2008 which turns on NV8 and XV8 and disallows many more characters.

I thought we were already relying on IDNA2008. Have you checked if there are existing valid names that this would invalidate?

@raffy

I think this works in all cases and lets the standard integrate new emoji w/o issue, with the penalty that we forever remember the list of grandfathered emoji to account for previously registered names, which seems pretty mild compared to breaking thousands of registered names.

It sounds like this will require manually evaluating every existing emoji to determine how to handle it. How big a job is this?

@raffy

It might we smart to deviate from this and say that only (.) [002E] is a stop and these other stops are bad:

This seems reasonable to me.
