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.
