How HTML Entity Encoder / Decoder works

HTML entities represent characters that have special meaning in markup, including angle brackets, ampersands, quotes, and non-breaking spaces. Encoding them helps display literal characters instead of letting the browser interpret them as HTML.

A browser text element is used to translate between characters and their entity-safe forms. Decoding resolves recognized named or numeric entities, while encoding replaces markup-sensitive characters with safe representations.

Entity encoding is context dependent. Text-node escaping is not a complete defense for URLs, CSS, JavaScript, or every attribute context, so production applications should use the escaping facilities provided by their template framework.
