character encoding wrong for some pages

Hi,

I've been pulling down pages from wiktionary in a Java application. The
majority of pages seem to work fine (e.g. http://en.wiktionary.org//wiki/-a).
I can load them in Java, and if I wget them, I end up with a file containing
what I'd expect.

However, some pages seem not to work (e.g.
http://en.wiktionary.org/wiki/absolute_instrument). In Java, I get a codec
exception and when using wget, the resulting downloaded file is garbled. I
think this is because although they claim to be UTF-8 encoded, they are not.
These pages show up fine in my browser, but it isn't telling me what charset
it uses to decode the text.

Is this a known issue? Is there any workaround for this? Can it be fixed
server-side?

Thanks,

Matthew
