Frequently asked questions

Which characters get encoded?

The five HTML-significant characters (& < > " ') are always encoded; you can also escape every non-ASCII character.

Is decoding safe?

Yes. Entities are resolved with the browser's parser and no HTML is executed; nothing is sent to a server.

Why encode HTML entities?

It prevents characters like < and & from being interpreted as markup, avoiding broken pages and injection issues.
