I am still poking at this issue, having got distracted by the one below, which I think is related but not the same. Note that the page you get redirected to on a saved edit is wrong, being http://vienna.openguides.org/vienna.cgi?Category_CD/Platten-Gesch%C3%A4fte instead of http://vienna.openguides.org/vienna.cgi?Category_CD/Platten-Gesch%E4fte This is because the node name parameter is not being properly URL-encoded before the Location: header is printed to STDOUT. This bug slipped in because I forgot that CGI::Wiki::Formatter::UseMod's ->node_name_to_node_param method doesn't actually URL-encode, but expects you to do it yourself after calling the method (this _is_ documented).

I think it perhaps should, since what I expect from that method is something I can bung into a URL and it will Just Work. However changing it to do that would break backwards compatibility and could lead to things being doubly-encoded, which would suck. Thoughts? I may punt this to cgi-wiki-dev as well.
