What does the Host: header look like for a Unicode domain. e.g. æon.com in the MOST STANDARD format (assuming RFC 5987? or is it something else?)?
I am developing a transparent proxy that will need to work across different browsers and languages.
Could you paste an example of a Host: æon.com HTTP header, same as a Wireshark Packet Dump would produce, un-decoded and specifically the Host: field.
International domain names are encoded in Punycode. “æon.com” is represented by “xn--on-0ia.com”.
