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.
