Do we therefore have support to introduce Puny code now and then consider how to move forward with UTF-8?
I'm not sure I understand the proposal. "punycode" is primarily IDNA2003 speak - and the initial suggestion by Ed was to apply an automatic conversion.
Correct, I propose to automatically convert non-ASCII IDN email address domains into Punycode, as per RFC 5891.
How would that system deal with conversion failures and/or with ambiguities between IDNA2003 and IDNA2008?
We plan to use a third-party Java library to convert Punycode, rather than implementing one from scratch (doing it ourselves would increase complexity and time taken). Any conversion failures will result in the attribute value being considered invalid. A workaround in that case is to manually convert the IDN to ASCII (Punycode).
