For an updated version 0.2, see taiku goes multilingual
Richard Suchenwirth 2002-03-15 - Since 8.1, a GIF image with the Chinese characters tai-ku has been included with Tcl. As I've never seen anybody use it, even less name a software after it, I now dare to present taiku, a little Chinese editor (tai-ku is supposed to mean "extremely cool", and especially Tcl ;-) which I hacked together in a day. (15 years ago it took me several weeks, in TurboPascal on a Z80 box...)
The main task was to write a little "input manager" that maps Latin keystrokes from the keyboard to the corresponding Chinese characters. Such input goes into an entry widget and, when validated, the selected Unicode is inserted into the text widget. Since the pronunciation spelled in pinyin is mostly ambiguous, a menu of 10 characters is presented wherever suitable. You select one of the characters by typing the associated digit, or can scroll through the whole "character space" of GB2312-80/Level 1 (which offers you 3755 most frequent characters) with the Up/Down keys. Most frequent characters are offered in the yellow "favorite" field; select them by just typing a space. (You might want to edit the list of favorites to include yours; you can also assign sequences of up to three Chinese characters to an input ASCII sequence). In the codes, all Chinese characters are addressed with their decimal GB2312-80 number (because that encoding is sorted by pronunciation - hooray for Tcl's smooth i18n support also regarding encoding conversions!).
Toggling between ASCII input (directly into the text widget) and "cim" (Chinese Input Manager) input (into the entry at bottom left) is done with the <Esc> key, or by clicking into the text resp. entry widget.
Printing is solved only for Windows 95..ME, where the only program able to print Chinese was Internet Explorer. Hence, a temporary HTML file is created and a browser window opened. You can adjust font size etc. there and let it print for you. And of course, on any box you'll need at least one Chinese font...

Chang LI: Absolutely Cool!
JimG 2005-04-25 I've never dreamed of such a cool thing in less then 200 lines (Tai Ku! could be Te Ku! sounds closer to Tcl). I've found there are a lot of magic things in Tcl and some Fun with Chinese Characters though I've just started to learn.
