Frequently Asked Questions
Which characters are encoded to HTML entities?
The critical characters are: & → &, < → <, > → >, " → ", and ' → '. These are the characters that have special meaning in HTML and must be escaped to display correctly.
Should I use HTML encoding to prevent XSS?
HTML encoding is an essential layer of defense, but it must be applied in the right context. Always encode user input before inserting it into HTML. For other contexts (JS, CSS, URLs), use the appropriate escaping method.
