Blissymbols, also known as Blissymbolics, is a unique constructed ideographic writing system created by Charles K. Bliss in 1949. The symbols represent concepts, allowing for communication between different linguistic communities. Bliss aimed to create an international auxiliary language inspired by Chinese characters. The system has been used to teach disabled people to communicate and has been popular in countries like Canada and Sweden. There was controversy surrounding the use and adaptation of Blissymbols, leading to conflicts between Bliss and educators. Despite this, Blissymbolics Communication International now holds the exclusive license for Blissymbols. The system has been standardized and proposed for inclusion in international character encodings.
