Comment (by tomdxw):

 I'd just iterate through the codepoints in wxr_cdata() and replace
 disallowed codepoints with U+FFFD (the replacement character). I'm not
 sure of the best way to iterate through codepoints in PHP - but UTF-8
 parsers aren't hard to write if there isn't already a function that does
 it.
