Content Cleaner

Automatically removes non-printable characters, including the ETX character, from content, title, and Advanced Custom fields.

The Content Cleaner plugin is an all-in-one tool for automatically removing non-printable characters from content and title fields. After building Wordpress sites for many years, one problem that consistently plagues my clients (especially the less tech-savvy ones) is non-printable characters in their content or in their titles. This plugin works by running a regular expression find and replace to clean up post content, post titles, and even Advanced Custom Fields. It's extremely lightweight and works without any setup required.

Will Content Cleaner delete things I don't want it to delete?

For most people, Content Cleaner won't appear to make any difference and won't remove anything from your content.

What is the regex you're running on the content?

All content and titles are run through a preg_replace function using this regular expression: '/[\x00-\x08\x0B\x0C\x0E-\x1F\x7F]/u'
