VaultPress security warning in version 2.0.1, potential false alarm

Hello,

I received a security warning form VaultPress after upgrading to version 2.0.1 of this plugin.

The warning was Generic.Hidden.Code.2 meaning “This file contains suspicious hidden code, and should be checked for recent changes, or malicious code.”

It was referring to this file: plugins/google-listings-and-ads/src/Polyfills/Normalizer.php

My best guess is it was triggered by this line containing hex characters:
https://plugins.trac.wordpress.org/browser/google-listings-and-ads/tags/2.0.1/src/Polyfills/Normalizer.php#L42

This seems like a false alarm to me, but I wanted to point it out just in case.

Thanks!
