Hi,
I have a web site with non-english cources and I run wiki on it. all information on english languages are search when I search a word in wiki search, but when I search a word in other languages I wiki search can't find anything.
Note:
cron.php was run successfully and it hasn't any problem. MySql DB support UTF-8 and also all tables are on UTF-8 support mode. also wiki shows all information without any problem on root page (I mean when I open wiki page it shows data with any languages without any error on views).
