Thread:Extension talk:Zend Search Lucene for MediaWiki/Special:PslZendSearchLucene, problems with display of Japanese/Chinese !/reply (6)

Ok, its fixed now. This problem was caused by the entry "de_CH.UTF8" within the indexing settings of Zend Framework. It must read "de_DE.UTF8" to work properly with special characters like ä, ö, ü, etc. So, finally no problems with the extension, thank you!
