Details:

Given a file that is not NFC-encoded, this expression fails:

(read-xml-file "/tmp/reproduce.xml")
;The object "\nx xxxxxxx xxxxxx xx xxxx xxxxxx xx xxxx xxxxxx xx xx xxxxx
xxxx, <x>xxx xxx xx xxxxx,</x> xxx xx xxxxxxxx xx xxx xxxxxxx xxx xxx xxxxxxx.
xxx “xxx xx xxxxx” xxx xxxx xxxx xxx xxxxxx xxxxx xxxx xxxx xxxxx. x xxx
xxxxx xx xx xxxxx xxxx xxxxxxxxxxx xxxx xxx xxxxx xx xxxxxxxxxx xxxxxxx xxx
xxxxxxxx xx xxx’x xxx xxxxxxxxxxxxx. xxx xxxx xxxx xx xxxxxxxxxxx xxxx xxx
xxxxx xx xxxxxxxxxx xxxx xxxxx xx xxxxxxxxxxxxx xxxx, xx xxxxxxxx xxxxxxx,
xxxxxxxxxxx xxx xx xxx xxxxx xxxxx xxxxxxxx xx xxx xxxx. (xxx ...", passed as
an argument to string-find-first-index, is not the correct type.
;To continue, call RESTART with an option number:
; (RESTART 1) => Return to read-eval-print level 1.

2 error> 

I've attached the offending file, which was part of a podcast feed.  In order
to avoid copyright issues, I've replaced [a-zA-Z] with "x" throughout the
textual content.

read-xml-file reads the same file file after normalization using Emacs's
ucs-normalize-NFC-region.
