[Therion] Encoding Simpleton

All the Windows applications I have do not recognise line feeds the way Xtherion does. They display Therion data files as one continuous stream of characters. I think it's probably as easy as changing the default encoding, but as I only speak one language, my knowledge is deficient in this area. I have no idea what I should change it to, ASCII would seem to be a good choice, but despite the Therion book saying it is supported, it does not appear in the drop down list in XTherion. Is there a way of enabling cross compatibility between Therion data files and Windows plain text editors or say Visual Basic editors in Windows, set up to use English (US, UK or NZ)?
