ASCII Code 128

About This Character

ASCII code 128 (0x80) represents the Euro sign character in the extended ASCII table (128–255). It is a widely recognized symbol used in international commerce, intellectual property, or mathematical notation. 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.
