Bundling vs Mapping

[Erik van der Poel]

I'd like to know what Eric meant when he talked about bugs and URIs.

Bidi is interesting, but even before you get into that, we have plain
old lower-casing. The question is whether browsers are going to
continue to lower-case as part of IDNA when they adopt IDNA20XX. The
next question is whether they are going to continue to perform NFKC as
part of IDNA. Then we have the question of Eszett. And at some point,
we have the question of bidi, but that is certainly not the first
question that comes to my mind.
