Ideographic Description Sequences

Ideographic Description Sequences

A list of Ideographic Description Sequences (IDS), created manually or by exporting compositional data from glyphs made under the hkcs namespace on GlyphWiki.

Decomposition Strategy

Characters are generally decomposed according to the principles set out in the IRG PNP. For example, 嬲 is decomposed to ⿲男女男.

Characters are not decomposed if they constitute separate productive components. For example, 王 is not decomposed to ⿱一土.

Vulgar characters with additional radicals (增旁俗字), e.g. the addition of 氵 added to waterfowl, are not combined with the phonetic component. For example, 𪈯 is decomposed to ⿲氵霍鳥 instead of ⿰氵鸖 or ⿰瀖鳥.

ids's Issues

U+7D75 絵 and U+7E4D 繍

Decompositions should use traditional 糸 rather than simplified 纟

U+7D75 絵
U+7E4D 繍

Bug exists in file release/ids-20230408.txt

U+8D67 looks wrong

Decomposition is recursive.

All three files in release folder exhibit this.

U+38DE 㣞 buggy

Decomposition of U+38DE 㣞 looks wrong.
