Thanks for the replies, I guess I may have missed earlier discussion.  I'd realized that I was working on what I thought was "an obvious assumption" and didn't recall much discussion about the issue.

Other than not requiring a mapping I don't see mention of this in the RFCs.  Did I miss it, or do we want to make the recommendation in one of the RFCs that users may want ASCII address to be in a friendly form (rather than encoded?)

I don't think this impacts the standard directly, but rather it may impact the thinking about the overall architecture of a system that works with such addresses.  Eg: if you design a single-sign-on system expecting Unicode addresses with encoded ASCII you may make different decisions that if you anticipated friendly ASCII forms.
