in thread pack() v unpack() padding: bug or ???

BrowserUk:

Since it specifies ASCIZ, I'd expect it to work like it does. Isn't 'a2' the behaviour you're asking for?

    It depends whether you mean the behaviour I'm looking for in the OP; or the behaviour I expect from Z; but actually, the answer is no in both cases.

    It's not a substitute for (my expected behaviour of) Z because it doesn't "null terminate", it only "null pads":

    C:\test>p1 print unpack 'C*', pack 'a2', $_ for qw[ fr x ];; 102 114 120 0

    And my OP question relates to unpack rather than pack. Athanasius picked up on a comment in a code sample that was more of a reminder to myself rather than a part of the OP.
