[docbook-apps] German umlaut in index

[Pool 475-1 FRD TE-N <Pool475-1 dot FRDTE-N at zf dot com>]

Hi,

I've got the same problem as stated in the mail with the subject
"DOCBOOK-APPS: autoidx: sorting of special characters" from Wed, 28 Nov 2001
(the essential part is pasted below). Is there a solution yet?

Thanks,
Bjoern


--- DOCBOOK-APPS: autoidx: sorting of special characters ---
i'm trying to produce an index for a document in german, and index terms 
starting with one of the german umlauts appear as symbols in the index 
(docbook-xml dtd 1.44). i put the unicodes for these characters into the 
"lowercase" and "uppercase" entities in fo/autoidx.xsl so these characters 
appear as additional characters in the index. that's nice, but in german 
indices, these characters usually are sorted as if they were "ae", "oe", and
"ue".

is it possible to modify the sorting rules for these special characters (and
maybe others in other languages)?
