ASCII Code 189

About This Character

ASCII code 189 (0xBD) represents the Vulgar fraction one half character in the extended ASCII table (128–255). It is a vulgar fraction character, providing a compact way to display common fractional values in text. The extended ASCII range builds upon the original 128-character ASCII set, adding accented letters, currency symbols, typographic marks, and mathematical symbols. These characters are defined by the Windows-1252 (CP-1252) encoding, which is a superset of ISO 8859-1 (Latin-1). In modern web development, UTF-8 encoding is preferred, but understanding extended ASCII remains important for legacy system compatibility and character encoding troubleshooting.
