HTML entity encoding is a fundamental security practice for web development. Any user-supplied content displayed in HTML should be entity-encoded to prevent script injection attacks. Convert in both directions: encode text for safe HTML insertion, or decode HTML entities back to readable text. Handles all standard named entities, decimal entities, and hexadecimal entity codes.
