CentOS 7.0 - man page for perl::critic::policy::valuesandexpressions::prohibitescapedcharacters (centos section 3)

Perl::Critic::Policy::ValPerl::Critic::Policy::ValuesAndExpressions::ProhibitEscapedCharacters(3)

NAME
       Perl::Critic::Policy::ValuesAndExpressions::ProhibitEscapedCharacters - Write
       ""\N{DELETE}"" instead of ""\x7F"", etc.

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

DESCRIPTION
       Escaped numeric values are hard to read and debug.  Instead, use named values.  The syntax
       is less compact, but dramatically more readable.

	   $str = "\x7F\x06\x22Z";			   # not ok

	   use charnames ':full';
	   $str = "\N{DELETE}\N{ACKNOWLEDGE}\N{CANCEL}Z";  # ok

CONFIGURATION
       This Policy is not configurable except for the standard options.
