Frequently Asked Questions
What are HTML entities?
HTML entities are special character sequences used to represent characters that have special meaning in HTML (like <, >, &, ") or characters that are not available on standard keyboards.
When do I need to encode HTML?
Always encode user-generated content before rendering it as HTML. Failing to do so allows malicious users to inject scripts — a vulnerability called Cross-Site Scripting (XSS).
What's the difference between named and numeric entities?
Named entities use a descriptive name (e.g., & for &). Numeric entities use the character's Unicode code point (e.g., & for &). Both are valid and produce the same output.
Does it handle Unicode and emoji?
Yes. Unicode characters and emoji can be encoded to their numeric HTML entity equivalents, ensuring compatibility across all browsers and email clients.
