Does an international Dvorak layout for Windows already exist?
Update: I'm looking for a Dvorak layout that is essentially the original US Dvorak layout but with international characters added somewhere. I'm not interested in a fully localized layout based on the Dvorak principle.
I'm using Qwerty but I'd like to switch to Dvorak. Problem: I need to write international characters that are not available on Windows' built-in US Dvorak! I need to type Danish (æøå, ÆØÅ) and German (äöü ÄÖÜ) characters.
I once made a custom Dvorak layout from scratch using MSKLC but later could no longer install that tool to bugfix my layout. (I haven't tried installing it on my new Win7 installation yet.)
PS: As far as I can tell, not even Linux (Ubuntu) has a Danish or German Dvorak layout, only Norwegian which is close enough - but isn't Windows.
PPS: This is not a discussion about Dvorak vs. Qwerty. I appreciate the arguments for both sides, but this is simply a question about where to get the layout.
