This text only talks about length restrictions, not about character
set differences. I have to re-read the mailing list archive to see
what exactly happened.

As a technical contributor, I think we look kind of foolish if we
restrict unicode usage due to some legacy interfaces.  The guideline
"Use 7-bit ASCII because of some protocols designed in the late 80s."
can't be the long term answer to internationalization. OSes really
have moved on. I can put fancy characters into my interface name on
Linux. The kernel does not care and the tools do work well with it.

/js (speaking as a technical contributor)
