I am translating
<TradeWith>Trade with {0}</TradeWith>
for
<TradeWith>Negocia amb {0_definite}</TradeWith>
getting: Negocia amb the Barry, comerciant (Nord Athinumys)
expected: Negocia amb la Barry, comerciant (Nord Athinumys)
So the article is not translated as expected.
I think it should work now since Catalan has its own language worker. Could you please confirm?
