The link generated for a tag with special characters in its name is double-escaped

[zackw]

If you have a tag with a name that's got URI special characters in it, e.g. "status:404 NOT FOUND", which contains spaces and a colon, the HTML generated for that tag will be something like

<a class="tag" data-tag-id="63786" data-tag-name="http-response:404 NOT FOUND"
   data-hub-id="1" data-hub-feed-id="12" data-hub-feed-item-id="127764"
   href="/hubs/1/tag/http-response%253A404%2520NOT%2520FOUND">http-response:404 NOT FOUND</a>

in which the special characters have been double-escaped when generating the link to the all-items-with-this-tag page. The correct link would be to /hubs/1/tag/http-response%3A404%20NOT%20FOUND.

These links are always generated with code of the form

link_to hub_tag_show_path(hub_id, u(tag.name)) ...

and I believe the problem is that u escapes URI special characters once, and then hub_tag_show_path does it again. However, I cannot find the documentation for u (which I presume is a Rails built-in) nor can I find the definition of hub_tag_show_path (which has to be somewhere in the TagTeam source code, but grep -r show_path * from the top level only brings up the uses!) so I cannot be certain of this.

This also affects all uses of hub_tag_rss_path, hub_tag_atom_path, and hub_tag_json_path. I can't find the definitions of those either.
