It would be nice, if you could tell us emacs-version and tramp-version.
Futhermore, could you, please, set debug-on-error to non-nil, and show
the backtrace?
Thanks, and best regards, Michael.

Thanks for the backtrace. The problem is the following line:
file-name-directory("/index.php?title=%E7%89%B9%E6%AE%8A:%E6%9C%80%E8%BF%91%E6%9B%B4%E6%94%B9&feed=rss")
It checks the local file name part of your URL. Unfortunately, due to
the leading "/" and the ":", it looks like a Tramp file name from
syntactical point of view, but it isn't.
I have committed the following patch towards the Emacs-23 branch (which
will be synchronized with the trunk next days):

IMHO this is the wrong place to fix that. Instead file-name-directory
should not be called on the local part in the first place, or at least
*all* file name handlers should be suppressed around the call.

I thought about that. But I'm not sure, whether we shall disable
jka-compr, for example. What happens, if the URL is something like
http://host.cc/path/file.gz ?
I do not know url*.el sufficiently, that I could decide this ...

Nothing special. Why should it? It's not a file name, it is a URL.

Maybe. But at least `url-file-handler' must be kept, it treats the URL
as a file name.
Another approach would be to encode ":" in the filename part of a URL,
but I don't know where to do it sufficiently.

Why? There is no url-file-name-directory.

Indeed. But you don't know, which other primitive functions are called,
requesting a url-* handler. And you don't know, whether
url-file-name-directory will be added to url-handlers.el in the future.
At least I don't know. If there shall be another fix than disabling
Tramp temporarily, I would like to give it to somebody else with much
more knowledge about the url package than I have.

??? We are talking about file-name-directory.

Even then, it will not be called because the argument does not match the
syntax of a URL, since it's only the local part of it.

I believe, such a mis-handling of the URL file name part can happen
somewhere else as well. So a more general solution might be useful.
For the concrete location of my patch you might be right. Let-bind of
file-name-handler-alist to nil should do the job as well.

They should be fixed as well.

But it will only hide the real problem.

Hmmm, it is probably due to the link having changed,

new http://taizhongbus.wikia.com/index.php?title=特殊:最近更改&feed=rss
But still, the error message should be more like the 404 Not Found the

It turns out I was using the right url
http://taizhongbus.wikia.com/index.php?title=特殊:最近更改&feed=rss i.e.,
http://taizhongbus.wikia.com/index.php?title=%E7%89%B9%E6%AE%8A:%E6%9C%80%E8%BF%91%E6%9B%B4%E6%94%B9&feed=rss
all along. So the problem is tramp.

The former two cause problems, but the latter three don't.
http://radioscanningtw.wikia.com/index.php?title=特殊:最近更改&feed=rss
http://taizhongbus.wikia.com/index.php?title=特殊:最近更改&feed=rss

http://transgender-taiwan.org/index.php?title=特殊:近期變動&feed=rss
So either there is something allergic in the URL's UTF bytes, or it is the
Wikia.com response that is causing the problem. The HTTP HEADs are all
200 but slightly different.
