Perl::Critic::Policy::ValuesAndExpressions::ProhibitEscapedCharacters - Write "\N{DELETE}" instead of "\x7F", etc.
This Policy is part of the core Perl::Critic distribution.
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
This Policy is not configurable except for the standard options.
