This doesn't seem like a bug in Emacs, and we didn't hear anything in 3
months.  I'm therefore closing this bug.

If this is still an issue, please reply to this email (use "Reply to
all" in your email client) and we can reopen the bug report.

Starting with `emacs -Q`:

(require 'xml)
(xml-escape-string "And now it\342\200\231s all this")

The result is: `xml-escape-string: Invalid XML character: 4194274, 
11`

I expect that the string will parse correctly with these escape 
characters. Or is this expectation wrong?
