ASCII Code 145

About This Character

ASCII code 145 (0x91) represents the Left single quotation mark character in the extended ASCII table (128–255). It is a typographic character used in professional publishing, quotation formatting, and editorial design. 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.
