Attached is a new patch that uses Unicode properties to select only printable base characters. Thanks, but my main question is still not answered. I asked it from the POV of documentation: we should provide a more specific description of which characters will be printed as characters, so that users are not surprised. The text in NEWS still says "printable characters" without defining that term, and so does the doc string of print-integers-as-characters. And now there's another question, which is what caused you to filter characters like you did? E.g., what's wrong with combining classes? why not simply use graphicp?
