[Koha-devel] proper sorting order and search for Swedish characters and ISBN search

[Gaetan Boisson]

Digging this back up as we finally found a solution. And by "we" i mean 
Fridolin Somers, whose knowledge of ICU, zebra and indexing never ceases 
to amaze me!

Setting the ICU locale to sv-SE was not enough it seems, because this 
still transliterated å, ä, ö, Å, Ä and Ö to a, o, A and O.

We just had to add a rule to exclude them from the transliteration:

<transform rule="[^åäöÅÄÖ] NFD"/><!-- do not undiactric some characters -->

Meh, sounds easy enough now!

Hopefully this will come in handy to someone.
