On Linux you can create any layout you wish by editing the appropriate ASCII configuration files. On Windows the keyboard layout definitions are binary. Is there any tool that can create these binary keyboard layout configuration files?
I grew up on the Macintosh international keyboard layout, which used the option key extensively, and now I would like to use the same layout on Windows.
On Linux this Mac international keyboard layout exists for both the console as well as for X.Org. On Windows, the most similar layout is US International, which is not the same.
