Popped over to the Catalan Wikipedia to see if I could find an article that [[en:Catalan Countries]] should be linked to there... noticed that interlanguage links show as plain text there, for example, the top of [[ca:Geografia]] looks like:
[[da:Geografi]] [[de:Geographie]] [[en:geography]] [[eo:Geografio]] [[es:Geografía]] [[fr:Géographie]] [[nl:Geografie]] [[pl:Geografia]] Ciències > Geografia
... in normal viewing.
