Nciku, a Web site that bills itself as “more than a dictionary,” has a nifty feature that allows users to find Chinese characters by drawing them with a mouse.
As you draw, possible character matches will appear in the box to the right of your drawing, with the results refined as your drawing progresses. You don’t need to know the canonical stroke order to get this to work, nor do your calligraphy skills need to be perfect, as this example shows.
Once you see the correct character offered as a choice, click on it and it will be entered into the search box for the site’s online dictionary. This dictionary feature can handle multiple-character input and will even prompt you with likely choices to fill out your search.
