Unicode 4.1 added a set of sixteen characters representing strokes used in writing Han characters at 31C0..31CF; and 20 more will be added at 31D0..31E3 in Unicode 5.1 (and additional extremely rare strokes may be proposed for encoding in the future).
The names of CJK stroke characters are rather abstruse, using a sequence of one or more letters to represent a sequence of one or more stroke elements, each letter being the first letter of the pinyin romanization for the Chinese character by which the particular stroke element is known :
