I installed dokuwiki twice on two local servers. At one of them umlauts are not treated correct in the searchindex. Everything looks fine with displaying umlauts, but my word.idx does not contain any umlaut words of the wiki. They are all diveded in two parts. For example: I have the word 'märkte' in the wiki, then word.idx contains rkte. Maybe it' a fault in the server configuration, but i cannot figure out where it is. I tried to re-index with searchindex manager, but that make no difference.
(maybe this task is wrong in the utf-8 section)
Can you give some additional info? What's the difference between both servers? Operating System, Webserver, PHP version? Do you have the mb_string extension available?
Hello Andi - the mb_string was the right hint. I activated it, now everything works. The Apache where i had the problems is installed as a module.
In another installation mb_string is not availible (PHP 4.3.3 with Apache as CGI), and it had no negative effect at all.
Thank's a lot for your help.
