I've made some progress and indeed the results are better if the geo
param is localised. At least for these combinations:
ca França / fr France / en Greece / it Libia / en Libya / en Algeria /
fr Maroc / en Morocco / en Portugal / pt Portugal / / en Spain / es
España
ca Espanya / en Italy / it Italia / de Italien / fr Italie / sl
Italija
The translation api has no results for Breton, Corsican, Western
Frisian, Basque, so no test/results.
Interestingly non ASCII param/country España works, however Arabic
(Cyrillic not. (e.g. bg България / ar (Algeria) الجزائر / ar (Libya)
ليبيا / ar (Egypt) مصر)
Are non-European languages supported? What about Turkish?
