Meaning of ideographic description sequence | Babel Free

Definitions

A sequence which, taken together, describes (or closely approximates) an ideograph, typically used to describe Han ideographs (Chinese characters) that have not been encoded, and therefore have no codepoint associated with them; comprised of a ideographic description character that gives a layout (e.g. ⿰, ⿸) or transformation (e.g. ⿿), followed by one or more components which that character operates on, which may be encoded characters or other sequences in the same format.
