RFC 2486bis specifies how the NAI is internationalized. In the
development of this document, some questions have arisen about the
behavior of existing EAP peers and RADIUS proxies. In order to understand
how existing implementations function, we need implementers to volunteer
the answer to several questions:
1. How is internationalization supported on your EAP peer implementation?
Does your EAP peer implementation support formating of the realm
portion in IDN, or does it enable entering of UTF-8, or perhaps just plain
ASCII?
