I saw that before.. they are not talking about IDN and EAI, only referring to email content.

I don't recall seeing this mentioned on the DL previously.  Just FYI.


RFC 8255 supports multi-language content in email (see: https://tools.ietf.org/html/rfc8255). At IETF 101, Nik Tomkinson has organized a hackathon on Saturday and Sunday to test (and presumably improve) running code:
https://www.ietf.org/mail-archive/web/slim/current/msg01304.html

There is also a specification for language negotiation in SIP (https://tools.ietf.org/html/draft-ietf-slim-negotiating-human-language), but this will not be part of the hackathon.
