Character Encoding Standards - TSV
Character encoding standards are specifications for representing characters as digital data in computers. Various schemes exist including ASCII, UTF-8, UTF-16, Shift_JIS, and EUC-JP, each with different character sets, byte structures, and compatibility characteristics. While UTF-8 has become the international standard widely adopted today, legacy encodings like Shift_JIS and EUC-JP are still used in Japanese computing environments.
