Hello, I noticed a behavior change somewhere in the Email::MIME
stack when header_str_set is passed a string with a single-quote
(') character in it.
On my Debian stable (stretch) machine the behavior is to
leave the single quote alone. On Debian unstable/sid,
a backslash is added before the single-quote.
Changes from stretch to current sid are as follows:
perl (including Encode.pm) 5.24.1-3+deb9u3 -> 5.26.2-3
libemail-mime-perl 1.937-1 -> 1.946-1
unchanged:
libemail-mime-encodings-perl 1.315-1 -> 1.315-2
(only Debian-specific packaging changes, I suspect)
I think the old behavior (not adding backslash) is correct, but
I'm not sure. I can work around the problem with "header_set"
instead.
use strict;
use warnings;
use Email::MIME;
my $mime = Email::MIME->create;
my $h = 'From';
my $n = q("Quoted N'Ame" <f...@example.com>);
$mime->header_str_set($h, $n);
print $mime->header($h), "\n"; # adds backslash to '
Konstantin hit this with public-inbox on CentOS but using newer
modules from CPAN and older Perl:
