I am using the Babel package to write a document in spanish. Everything seems to work fine except for the quotation marks: " and " (actually they are the same symbol, but come in pairs). The problem I am experiencing is inconsistency, sometimes they work correctly some times I get strange symbols like ç.
Looking online I found one solution is to use the symbols: `` ''. I was wondering if there is a way to make the symbol " to work correctly, or maybe other consistent solution.
