wikipedia link: w3m does not found anchor

[Harald Maier <harald@xxxxxxxxx>]

This bug report will be sent to the emacs-w3m development team,
 not to your local site managers!!
Please write in simple English, because the emacs-w3m developers
aren't good at English reading. ;-)

Please describe as succinctly as possible:
	- What happened.
	- What you thought should have happened.
	- Precisely what you were doing at the time.

Please also include any Lisp back-traces that you may have.
================================================================
Dear Bug Team!

M-x w3m-goto-url
"http://en.wikipedia.org/wiki/Anton%C3%ADn_Dvo%C5%99%C3%A1k"
On that page goto  "Contents" -> "Symphonies" and press RET

emacs-w3m prints:
No such anchor: Symphonies
