Why do I need to HTML-encode text?

Unescaped HTML characters can break page layout or, worse, allow cross-site scripting (XSS) attacks. Encoding ensures text is displayed as-is, not interpreted as HTML.

Which characters are encoded?

The five essential characters: & (ampersand), (greater than), " (double quote), and ' (single quote/apostrophe).

Is this the same as URL encoding?

No. HTML encoding uses named entities (like &) for HTML display, while URL encoding uses percent notation (like %26) for URLs. They serve different purposes.
