Q.No.6 Define Unicode. Describe UTF-8 and UTF-16 Coding Schemes.
سوال نمبر 6 یونی کوڈ کی تعریف کیجیے۔ UTF-8 اور UTF-16 کوڈنگ سکیمز بیان کیجیے۔
Answer:Unicode is a universal character-encoding standard that gives a unique number (code point) to every character of every language, symbol and emoji, so text can be shared across all systems.
- UTF-8: variable-length encoding using 1 to 4 bytes per character. ASCII characters use only 1 byte, so it is backward compatible with ASCII and efficient for English text. Most widely used on the web.
- UTF-16: variable-length encoding using 2 or 4 bytes per character. Common characters take 2 bytes; rare ones use 4 bytes (surrogate pairs). Used in Windows, Java and JavaScript.
| Feature | UTF-8 | UTF-16 |
|---|---|---|
| Bytes per character | 1 – 4 | 2 or 4 |
| ASCII compatible | Yes | No |
| Best for | Web / English text | Asian scripts / OS internals |
