While it is true that there are various standards for encoding international characters in ASCII, at present none of them are applicable to email addresses. Phrases and comments in message headers are another matter. There are standards for internationalizing those (RFC 2047 in particular). But they don't apply to addresses themselves. > So the pure negative is: raw (binary) international characters are not > permitted. > The positive is: Encoded international characters are permitted. You certainly can perform such an encoding and produce a valid address, but there's no encoding that is standardized for email addresses so don't anyone else to reverse the encoding and display the result.
