I tried to add a german dictionary by exactly following the steps in your "Tips and Tricks" Section. I even downloaded the dictionary from the site you recommended. I treid the ASCII and the UNICODE versions. But it doesn't work - the german spelling is completely ignored, which is very annoying in long notes.
now, the ASCII Dictionary will not do. You've to convert it into UTF-8, then the German Umlauts are correct.
very sorry for that. could you try to search out other dictionary files?
