This plugin adds a shortcode that when used inserts an escaping checker. The checker gives you a form you can enter potentially unsafe content into, and when submitted, passes that content through every sanitisation, validation and escaping function in WordPress Core, and some PHP Core functions

Escaping Checker

Very useful

A handy tool for checking the output of escaping, sanitization and validation functions
