Frequently asked questions
What are HTML entities?
HTML entities represent special characters using named or numeric references so they can be safely represented in HTML text.
Why encode HTML characters?
Encoding characters such as <, >, quotes and ampersands can prevent them from being interpreted as markup when text is displayed as HTML.
Can I decode named entities?
Yes. The decoder uses the browser's HTML parsing behavior to turn entity references back into characters.
Does encoding make arbitrary HTML safe for every context?
No. Context-specific output encoding is still required for security-sensitive applications.
