Encodings

Simplified extremely:

  • Computers operate on numbers only, so in order to represent chars, some mapping is needed. Basically, encoding means this mapping.
  • ASCII (American Standard Code for Information Interchange) - mapping from 1-byte numbers to characters, can represent up to 255 chars (but uses only first 128). Covers all English letters, numbers, punctuation and some special chars.
  • ANSI code pages - standardized set of encodings which extend ASCII. They represent different non-English characters using next 128 numbers. Example: Windows-1251.
  • Unicode - next level of abstraction. Aims to represent all possible chars by mapping not directly to numbers, but to special codes (code points).
  • UTF-8, UTF-16 etc - Unicode encodings. Control how code points are mapped to bytes. UTF-16 encodes each code point using from 2 to 4 bytes. It isn’t backward compatible with ASCII, thus not very popular. Instead, UTF-8 uses from 1 to 4 bytes, and is compatible with ASCII (encodes first 128 chars the same way as ASCII).
