I'm doing a genart review of draft-ietf-lamps-e2e-mail-guidance-14.
As usual I checked for nits using https://author-tools.ietf.org/idnits.

Typically this turns up a few non-ascii warnings due to author names, 
which I ignore. But this doc has bigger issues. It has many examples 
containing stuff like:

└┬╴multipart/signed; protocol="application/pkcs7-signature"
  ├─╴[protected part]
  └─╴application/pkcs7-signature

It certainly looks prettier than doing something similar with ascii 
characters, but making that change wouldn't harm the readability of the 
document.

Is this sort of usage now allowed?

	Thanks,
	Paul
