If you want to sort A and A-ring together, you might also sort P and R together based on their visual similarity, also E-F, O-Q, C-G, U-V-W (V and W are sometimes sorted together in Swedish, although that practice is becoming less common. But they still teach in first grade that the alphabet has 28 letters: A-Z, Aring, Adiaresis, Odiaresis, excluding W.) Many Swedes I know that regularly work on US-ASCII terminals prefer using brackets and braces for the letters after Z, rather than typing either a-a-o or aa-ae-oe. At least the brackets are distinct, and cannot be read as anything else. > There are at least a few real world applications (I don't talk about > trivialities like UNIX ls), e.g. catalogs of international libraries, > where an _easy_ to understand language independend sorting standard would > be extremely useful.

For this application, I think English sorting order is rather well established. That doesn't mean language-adapted sorting conventions will disappear, especially in countries like Sweden, Norway and Spain where characters with diacritical combinations are considered distinct and inseparable from their "base letters". /hpa -- INTERNET: hpa@nwu.edu TALK: hpa@delta.eecs.nwu.edu BITNET: HPA@NUACC IBMNET: 16331@IBMX400 HAM RADIO: N9ITP NeXTMAIL: hpa@lenny.acns.nwu.edu Keyboard not found, press F1 to continue or Ctrl-Esc for setup
