HAH. Which version of the standard do you want to read? :-P
The short answer is: modern email systems should support it, if the address is injected into the mail-stream using quoted-printable format. As a binary (unescaped) character in an email header, no it isn’t supported. Regards, Michael B.

[mailto:[email protected]] Sent: Wednesday, January 28, 2009 2:04 PM To: MS-Exchange Admin Issues Subject: Is this a valid character to use for e-mail? Is this: Ÿ A valid character to use in the left-hand portion of an e-mail address? My google-fu is not working well for this… For example: imnotfindinganÿ[email protected] Might be the e-mail address in question. I have no idea how the character was originally entered—I’ve been cutting and pasting in notepad. We have some third-party listserv software that is choking on this and I’m trying to figure out if it’s valid.
