Our system recognises 3 word addresses in Latin-script languages when entered with or without the diacritics.  For example, typing ///demarquage.bruloir.meridien will take you to ///démarquage.brûloir.méridien on the map (displayed with the correct diacritics of course!).  We also allow common alternatives for diacritics and special characters, e.g. the system will recognise 'schoene' as 'schöne' (German), 'soeur' as 'sœur' (French) and 'oejet' as 'øjet' (Danish).
