What Is HTML Encoding?
HTML encoding replaces characters that have special meaning in HTML — &, <, >, " and ' — with their corresponding entity codes (&, <, >, ", '), so that text containing those characters displays correctly instead of being misinterpreted as markup.
This matters whenever raw text (like a username, comment, or code snippet) needs to be safely displayed inside an HTML page without accidentally being parsed as tags or breaking the page's structure.
