| Subject: | Changes to CGI::Util method escape breaks compatibility to CGI::Compress::Gzip |
We are using CGI and CGI::Compress::Gzip to automatically compress
output of html (Indirectly by using CGI::Application and
CGI::Application::Plugin::CompressGzip).
After updating from CGI V 3.29 to V 3.33 the output seemed to be created
as UTF-8 independent from the charset settings in the file or header.
This was for pages adding cookies to the header.
After examining the code it turned out that changes in the method escape
in CGI::Util from
$toencode = eval { pack("C*", unpack("U0C*", $toencode))} || pack("C*",
unpack("C*", $toencode));
to (change from "C*" to "U*" in the first pack call)
$toencode = eval { pack("U*", unpack("U0C*", $toencode))} || pack("C*",
unpack("C*", $toencode));
Caused the problem.
I don't know if this problem can be solved in this module because CGI.pm
caused the problem. I've report this also to the CGI module RT.
Thank you for your help and your great module. Happy new year.
