Perl::Critic::Policy::InputOutput::RequireEncodingWithUTUseryContributed Perl Perl::Critic::Policy::InputOutput::RequireEncodingWithUTF8Layer(3pm)

NAME

       Perl::Critic::Policy::InputOutput::RequireEncodingWithUTF8Layer - Write "open $fh, q{<:encoding(UTF-8)}, $filename;" instead of "open $fh,
       q{{<:utf8}, $filename;".

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       Use of the ":utf8" I/O layer (as opposed to ":encoding(UTF8)" or ":encoding(UTF-8)") was suggested in the Perl documentation up to version
       5.8.8. This may be OK for output, but on input ":utf8" does not validate the input, leading to unexpected results.

       An exploit based on this behavior of ":utf8" is exhibited on PerlMonks at <http://www.perlmonks.org/?node_id=644786>. The exploit involves
       a string read from an external file and sanitized with "m/^(w+)$/", where $1 nonetheless ends up containing shell meta-characters.

       To summarize:

	open $fh, '<:utf8', 'foo.txt';		   # BAD
	open $fh, '<:encoding(UTF8)', 'foo.txt';   # GOOD
	open $fh, '<:encoding(UTF-8)', 'foo.txt';  # BETTER

       See the Encode documentation for the difference between "UTF8" and "UTF-8". The short version is that "UTF-8" implements the Unicode
       standard, and "UTF8" is liberalized.

       For consistency's sake, this policy checks files opened for output as well as input, For complete coverage it also checks "binmode()"
       calls, where the direction the operation can not be determined.

CONFIGURATION

       This Policy is not configurable except for the standard options.

NOTES

       Because "Perl::Critic" does a static analysis, this policy can not detect cases like

	my $encoding = ':utf8';
	binmode $fh, $encoding;

       where the encoding is computed.
