I'm wondering if anyone on this list can help with answering the
question(s) raised in the following thread at perlmonks:
http://www.perlmonks.org/?node_id=752220
The basic issue is the difference between 5.8 and 5.10 with regard to
this one-liner:
perl -Mencoding=utf8 -le 'printf "%x\n", ord(chr(193))'
On 5.8.8 (encoding.pm v2.02, utf8.pm v1.06), that produces "c1" (hex for
193.)
On 5.10.0 (encoding.pm v2.06, utf8.pm v1.07), it produces "fffd" (unicode
replacement character.)
I'm assuming it has to do with how utf8::upgrade works in the context of
"use encoding qw/utf8/", but I couldn't see any real code difference when
comparing the two versions of utf8.pm, and likewise for the two versions
of encoding.pm.
So (just curious), what caused the change, and was it intentional?
Perhaps the docs for encoding.pm should clarify whether it makes (no)
sense to have "use encoding 'utf8';" in one's perl script?
Thanks,
David Graff
