Reference

How does the HTML entity encoder work?

HTML entities are special character references that prevent characters from being interpreted as HTML markup. Encoding converts characters like <, >, and & to their entity forms (<, >, &). Decoding reverses the process. Named entities use HTML5's standard names; decimal and hex use Unicode code points.
