I don't see the relevance to R-help. But the answer to your subject is unambiguous: valid URLs do not contain `special' characters -- they must be encoded. See RFC1738 at e.g.

At some point (probably 2.2.0) I intend to ensure that the mapping to file:// URLs that is done is a few places is encoded as necessary. This will likely result in a utility function filePathToURL or some such.
