That depends whether you want a console editor, or GUI editor. I think
that there is little need for a GUI editor, anymore. After all Qt's TextEdit
control is pretty complete and has most of the rendering code for complex
scripts right. Console editors are a different matter, I think.

Still, writing an editor is something you do for fun, not because it
really fills a need. (I should know - I've started writing an editor
in Python, just to see whether it would be doable.) A nice book about
writing editors is: http://www.finseth.com/~fin/craft/index.html, and
if all you want is how to learn to wrap a GUI edit control and a discussion
of the problems of Unicode editors, you might want to read (or even buy!)
my book: http://stage.linuxports.com/pyqt/, which is about writing
application in Python, and uses an editor as the leading example.
