Actually, it doesn't depend on the Language or Country but rather the Code Page. Ä is the upper-case of ä no matter what language you're using. The relationships between languages, keyboard layouts, and countries are very confusing and not at all straightforward. DOS has some internal functions to process case conversions (e.g., INT 2F.1213).
