Hi Henri-Damien

The ordering of characters/words in Zebra is fully configurable, so I am 
sure you can obtain the results you want. But first some fast answers:

What _is_ the correct alphabetical order ??  This depends very much on 
language in use, local variants, if-or-if not you want special 
characters included or not, etc ...

There are no special characters in Zebra, but there are default config 
files which drop certain common 'special' characters on the floor when 
indexing.

Have a look at http://www.indexdata.com/zebra/doc/fields-and-charsets.tkl
or your local
tab/default.idx
file to see which charmaps you have defined in your installation.

And especially
http://www.indexdata.com/zebra/doc/character-map-files.tkl
or your local
tab/*.chr
files to see what characters are mapped to nothing
('space' directive), or are ordered in which order you want
('lowercase' and 'uppercase' directive).

You are free to make copies of these standard files, hack them according 
to your needs, and include the new charmaps i your default.idx config file.

Hope that helps,
