Frequently Asked Questions

What are HTML entities?▾

HTML entities are special codes that represent characters in HTML. They start with & and end with ;. For example, < represents <, & represents &, and © represents the copyright symbol. They prevent browsers from interpreting characters as HTML tags.

Why should I encode HTML entities?▾

Encoding prevents cross-site scripting (XSS) attacks by ensuring user input is displayed as text rather than executed as HTML or JavaScript. It also ensures special characters like <, >, and & display correctly on web pages.

What is the difference between named and numeric HTML entities?▾

Named entities use descriptive names like &amp; for &. Numeric entities use the Unicode code point like &#38; for the same character. Named entities are more readable but only cover common characters; numeric entities can represent any Unicode character.

Can I use HTML entities for emojis and special symbols?▾

Yes. Any Unicode character can be represented as a numeric HTML entity using its code point. For example, the heart symbol can be written as ❤ and emojis can be expressed as 😀 using hexadecimal notation. This is useful when your HTML file's character encoding might not support the character directly.
