HTML 4.0 declares the character set to be the first 17 planes of ISO
10646, meaning that references up to 1056768 are allowed, although
there are some holes in between.
That is, something like this, but in the char ref handler, which I
don't know what should look like:
def unknown_charref(self, ref):
if ref<9 or ref==11 or ref==12 or (ref>13 and ref<32) or \
(ref>126 and ref<160) or (ref>55295 and ref<57344):
raise BadHTMLError, ('Illegal character reference: &#' + ref + ';')
# accept and insert
raise BadHTMLError, ('Unsupported character reference: &#' + ref + ';')
I think we should look at the SGML declaration of HTML, outlaw the
characters not supported by HTML 4.0 and raise
| On a side note, the Unicode issue seems to be heading for using /F's
| Unicode type. This would seem to be a good argument to drop MvL's
| Unicode type, which is currently in the XML tree, and replace it

Go for it!
