search content with special characters fails - FCK

hi list,

we just got the problem that contents stored by the FCK-Editor are not being found by the search - if they contain special characters.

E. g. the searchterm: "türe" doesnt return any results, cause it is persisted as "türe" by the FCK-Editor...

Does anybody know a solution for this? I know that it is possible to tell the FCK not to encode, but if i do so - i have to encode at rendering the view - and this is not possible because the content storde by the FCK contains HTML tags.

thx a lot for any advices

greetings
rainer
