Any code between 0x110000 and 0x3FFF7F are valid as character. Some of them correspond to a certain character set, some are not. For the latter, only utf-emacs can encode, and they can't be displayed with any font. But still they are valid as characters. For instance, you can set any syntax/category/char-code-property to them. --- Kenichi Handa handa@ni.aist.go.jp
