What does HTML Entity Encoder do?
Encode special characters as HTML entities or decode entities into text. Review escaping in markup examples and text output without treating it as universal XSS protection.
Interpreting results and common questions
Does entity encoding prevent every injection?
No. HTML text, attributes, JavaScript, CSS and URLs have different parsing rules. Match encoding to its context; it does not replace safe templates or HTML sanitizers.
