Frequently Asked Questions
What is Unicode and why is it important?
Unicode is a universal character encoding standard that assigns unique numbers to every character, symbol, and emoji across all languages. It enables consistent text representation across different systems and platforms.
When should I use Unicode escapes in JavaScript?
Use Unicode escapes when you need to include special characters in JavaScript strings that might not display correctly in your source code, or when working with characters outside the ASCII range in JSON data.
What are HTML entities and when should I use them?
HTML entities are codes that represent special characters in HTML. Use them for characters that have special meaning in HTML (like < and >) or for characters not easily typed on a keyboard.
What is UTF-8 encoding?
UTF-8 is a variable-length encoding that can represent any Unicode character using 1-4 bytes. It's backward compatible with ASCII and is the most widely used encoding on the web.
How do I handle emojis in my applications?
Emojis are Unicode characters that require proper encoding support. Use Unicode escapes or ensure your database and application stack fully supports UTF-8 to handle emojis correctly.
What's the difference between code points and UTF-8 bytes?
Code points are the abstract Unicode numbers assigned to characters, while UTF-8 bytes are how those characters are actually stored in memory. One character can have multiple UTF-8 bytes.
