Comment 1. 

Category: Normative change to existing feature retaining the original intent

Committee Draft subsection: 5.2.1

Title: Source character set values


Detailed description:

While investigating universal character names, I have realised that there
does not seem to be any requirement on the characters in the source
character set to have positive values, or even to be non-zero!  6.8.1
Conditional inclusion paragraph 3 adds a little implementation-definition,
but not much.  I suggest replacing the following sentence in paragraph 3:

    In both the source and execution basic character sets, the value of
    each character after 0 in the above list of decimal digits shall be one
    greater than the value of the previous.

by:

    In both the source and execution basic character sets, the value of
    each character in the above list shall be strictly positive, the value
    of zero shall not correspond to any printing character, and the value
    of each character after 0 in the above list of decimal digits shall be
    one greater than the value of the previous.
