ASCII and Character Encoding Basics
How ASCII codes work and how they relate to Unicode and UTF-8.
ASCII assigns numeric codes to 128 characters (0–127). Extended ASCII and Unicode expanded this to support international characters. UTF-8 encodes Unicode using variable-length byte sequences.
Common ASCII codes
- A = 65, a = 97
- 0 = 48
- Space = 32
- Newline (LF) = 10
- Tab = 9
