+=head1 NAME
+
+Perl::Critic::Policy::ValuesAndExpressions::ProhibitEscapedCharacters - Write C<"\N{DELETE}"> instead of C<"\x7F">, etc.
+
+=head1 AFFILIATION
+
+This Policy is part of the core L<Perl::Critic> distribution.
+
+
+=head1 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
+
+
+=head1 CONFIGURATION
+
+This Policy is not configurable except for the standard options.
