HTML Entity Encode / Decode
Escape HTML special characters (< > & " ') into entities to safely display raw text/code on a page, or decode entities back.
How it works
Encode replaces the five XML-safe special characters (&, <,
>, ", ') with their named entities, so HTML/code can be rendered as
literal text on a page instead of being parsed as markup. Decode reverses common named
entities (like , ©, …) plus any numeric
entity (A or A).
