ASCII vs Unicode

ASCII (American Standard Code for Information Interchange) defines 128 characters — the English alphabet, digits, and common symbols. Unicode extends this to over 140,000 characters covering virtually every script in use today. Every ASCII character is a valid Unicode character (U+0000 to U+007F). Unicode can be expressed in many notations: U+0041, hexadecimal 0x41, decimal 65, or binary 01000001 — all representing the letter 'A'.
