2 years ago I asked, on this newsgroup, how to weed out non-UTF-8
characters from my RSS feed. I was told that I could not do so with
certainty, but I could try various tricks that would give me maybe
99%. I notice, however, that XML parsers seem to have 100% certainty
when they find bad characters. Consider the last error that I get from
this validation service:
http://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fwww.ihanuman.com%2FpdsFiles%2Frss2221.xml
What PHP code would give me this kind of 100% certainty? It seems to
me that, whatever the XML parsers do to determine a bad character, I
could also do, so as to make sure no such character makes it into my
feed.
