Ideographic Description Characters is a Unicode block containing graphic characters used for describing CJK ideographs. They are used in Ideographic Description Sequences (IDS) to provide a description of an ideograph, in terms of what other ideographs make it up and how they are laid out relative to one another.IDS are described in [https://www.unicode.org/versions/Unicode9.0.0/ch18.pdf#page=23 chapter 18.2 of the Unicode Standard 9.0] on pages 689 through 692. An IDS provides the reader with a description of an ideograph that cannot be represented properly, usually because it is not encoded in Unicode; rendering systems are not intended to automatically compose the pieces into a complete ideograph, and the descriptions are not standardized.

U+2FF0 to U+2FFB were introduced from GBK; U+2FFC to U+2FFF were devised later and introduced in Unicode 15.1 (2023).

Block

Ideographic Description Sequences

Ideographic Description Sequences are sequences of characters that represent a Chinese character structure as defined by the Unicode standard.

Below are the 16 characters as defined by Unicode in this block:
