Frequently Asked Questions
What are HTML entities?
Special sequences like < that represent characters (e.g. <). Used to display <, >, &, and quotes safely in HTML.
When should I encode?
When inserting untrusted or user text into HTML. Encoding prevents the browser from interpreting it as tags or script (XSS).
Decode vs encode?
Encode: turn < into < for safe display. Decode: turn < back into < when you have entity text and need plain characters.
