--------------------------------------
Status: Held for Document Update
Type: Technical

Reported by: Vitaliy V. Tokarev <[email-masked]>
Date Reported: 2017-04-16
Held by: Alexey Melnikov (IESG)

Section: 3.3

Original Text
-------------
The definition of <atext> is extended to permit both the RFC 5321
definition and a UTF-8 string. That string MUST NOT contain any
of the ASCII graphics or control characters.

Corrected Text
--------------
The definition of <atext> is extended to permit both the RFC 5321
definition and a UTF-8 string. That string MUST NOT contain any
of the Extended ASCII graphics (%d128-255) or control characters.

Notes
-----
The question is: what is "ASCII graphics characters"? Either meant that is possible to transmit 8bit characters, but they should not be in range %d128-255. Or something else. A better clarification is appreciated.
