== Why is this an issue?

Entries in the ASCII table below code 32 are known as control characters or non-printing characters. As they are not common in JavaScript strings, using these invisible characters in regular expressions is most likely a mistake.

=== Noncompliant code example

[source,javascript]
----
const pattern1 = /\x1a/;
const pattern2 = new RegExp('\x1a');
----

=== Compliant solution

[source,javascript]
----
const pattern1 = /\x20/;
const pattern2 = new RegExp('\x20');
----
