I thought the encoding of wgPageName matched wikiUrlencode. However, that's not 100% the case, the so there are mismatches for certain cases, like those with parens.
For example, on Heissler of Heitersheim (Donat John Count):
wikiUrlencode: Heissler_of_Heitersheim_%28Donat_John_Count%29
wgPageName: Heissler_of_Heitersheim_(Donat_John_Count)
This will cause some title matches to be missed, resulting in the tour not showing.
