All of the Spanish special characters (á,é,í,ó,ú,ñ) are being substituted in the URL addresses as a hyphen ("-"). I would like to change this the following way: á|a, é|e, ... and so on. Should I enter in the Non-ascii character replacements section the data that way?

that's exactly whay I've done, with the capital letters too, and it works perfectly!
