Q:

Programmatically determine number of strokes in a Chinese character?

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

A:

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.

A:

In Python there is a library for that:
>>> from cjklib.characterlookup import CharacterLookup
>>> cjk = CharacterLookup('C')
>>> cjk.getStrokeCount(u'日')
4
