Thread:Extension talk:Zend Search Lucene for MediaWiki/Invalid argument supplied for foreach() in C:\xampp\htdocs\PslZend SearchLuceneIndexer.php on line 421/reply (6)

Yes, we have tried this extension in a Japanese environment an failed to used it. You have to consider that when running Apache and Mysql on a real Japanese OS based Windows or Linux environment that this might as well influence in how XML data (especially when you save data on that system) are handled (processed). Assuming that just because it is an UTF-8 enabled extensions does not automatically stand the real test in dealing with Chinese, Korea or Japanese characters, as in in our case we are using SphinxSearch which deals with all sorts of characters.

Just to clarify on the topic Semantic MediaWiki so people that get the wrong impression, it is not a modified MediaWiki, it is an extension (similar to this extensions) that uses standard hooks and parser functions to communicate with the data available from MediaWiki, their are no modifications that influence the standard functionality of MediaWiki nor does it in any away interfere with the database structure.
