These are visibly displayed graphic symbols, used in notations for the basic description and classification of the composition for any CJK ideograph or their variants. They are not intended to be used as invisible composition format controls to effectively render any CJK ideograph, and they do not describe their variable style (such as serif or sans-serif, weight, slant, calligraphic brush-painting, handwritten cursive, simplifications and joined strokes, ligatures, or additional decorations and colors).
Note that the four ideographic description characters U+2FFC to U+2FFF at end of this block were added in Unicode 15.1, and may not be rendered correctly unless some updated font is installed on your system. They should display a dashed square box containing either a smaller dashed box division for the first two (like characters above), or dashed arrows for the last two (not an X cross in a rectangular box, which would make them confusable with the special CJK indicator U+303F).
See also the two special CJK indicators U+303E and U+303F in the CJK Symbols and Punctuation block, and another ideographic description character U+31EF in the CJK Strokes block.
Ideographic description strings start by one these characters, followed by a defined number of components, which may be CJK radicals, strokes, ideographs, symbols or ideographic description strings.
