When I generate my index with XeLaTeX using xindy as described here: How to use xindy with XeTeX/LuaTeX? I struggle with proper ranges being displayed. Essentially, the dashes are missing and the page numbers stick to each other.


index a
index a b
index a b ä
index a b ä ü


This results in the following output:


As you can see, the a is shown with 14 instead of 1-4. My call to xindy was the following:

xindy -M texindy -C utf8 -L german-duden xindy.idx

The xindy.idx file looks good to me:


But the resulting xindy.ind file already shows the problem:


  \item a, 14
  \item ä, 3, 4


  \item b, 24


  \item ü, 4


What am I missing here?

It looks as if you must load an ranges module. E.g.

xindy  -M texindy -M page-ranges -C utf8 -L german-din test-utf8.idx


xindy  -M texindy -M ff-ranges -C utf8 -L german-din test-utf8.idx

(From the latex companion I would have expected the first to be loaded automatically but it doesn't seem to be the case).

You are absolutely right. page-ranges is not loaded automatically (for whatever reason) and when I include it explicitely, it works as expected. – kongo09 Sep 21 '11 at 19:17
By the way, one funny thing I noticed is that my xindy reports version 2.4 while on the xindy.org website sourceforge.net/projects/xindy/files it says the latest version is 2.3. Strange... – kongo09 Sep 21 '11 at 19:21
OK, this helped me a lot. But how can I find more modules on my system? page-ranges displays a 2 page entry as on page “1, 2”, which is wrong. It should be “1–2”. “1,2” suggests independent 2 occurences, while “1–2” implies a long text that spans 2 pages. Is there a module that does know exact this difference? – NobbZ Jul 29 '14 at 23:09

I run

texindy -C utf8 -L german-duden <file>.idx

then I get the following output:
