# Perl::Critic::Policy::ValuesAndExpressions::ProhibitEscapedCharacters(3pm)

Write ""\\N{DELETE}"" instead of ""\\x7F"", etc.

## 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.
