ISCII

A character encoding standard developed by the Government of India for representing Indian language text in digital systems. ISCII uses a single encoding scheme that can represent characters from all major Indian scripts by exploiting their common phonetic structure — each script maps the same sounds to the same code points, with the script being determined by a mode switch. ISCII was an important precursor to Unicode's representation of Indian scripts and was used in early Indian language computing systems, including assistive technology tools for visually impaired users.
