Programmatically determine number of strokes in a Chinese character?

Question

Does Unicode store stroke count information about Chinese, Japanese, or other stroke-based characters?

A little googling came up with Unihan.zip, a file published by the Unicode Consortium which contains several text files including Unihan_RadicalStrokeCounts.txt which may be what you want. There is also an online Unihan Database Lookup based on this data.

In Python there is a library for that:

>>> from cjklib.characterlookup import CharacterLookup
>>> cjk = CharacterLookup('C')
>>> cjk.getStrokeCount(u'日')

thanks for the great package! Today I tried it with these changes: 1. pip install cjklib3; 2. "C:\Users\your_name\AppData\Local\Programs\Python\Python310\Lib\site-packages\cjklib\util.py" needs a change to "from collections.abc import MutableMapping" from "from collections import MutableMapping"; 3. "cjk = characterlookup.CharacterLookup('C')" rather than "cjk = CharacterLookup('C')" – Mark K Jun 06 '23 at 03:38

You mean, is it encoded somehow in the actual code point? No. There may well be a table somewhere you can find on the net (or create one) but it's not part of the Unicode mandate to store this sort of metadata.

If you want to do character recognition goggle HanziDict.

Also take a look at the Unihan data site:

http://www.unicode.org/charts/unihanrsindex.html

You can look up stroke count and then get character info. You might be able to build your own look up.

UILocalizedIndexedCollation can be a total solution.

first, call "UILocalizedIndexedCollation sectionForObject:collationStringSelector:" to get an index of section. then back to check which section this index mapping to in "UILocalizedIndexedCollation.sectionTitles" – Jerry Juang Mar 27 '14 at 17:43
This is actually an Apple Eco-system only solution. – smat88dd Aug 01 '22 at 08:22
