No search results with ?ü?, could it be Multibyte string functions

  • Hi,

    I recently transfered to a windows server and got “Multibyte string functions are not available. Relevanssi may not work well without them. Please install (or ask your host to install) the mbstring extension.”

    As everything went smooth I did not care. However, I know realized that searches that include German umlaute (??üü??) have no search results. But for example Düsseldorf is in the index (I checked in database).

    If I deactivate Relevanssi it also brings up all pages with Düsseldorf in it. Only with Relevanssi it does not. Still, the_search_query() on search.php echoes Düsseldorf and all other search terms without umlaute work.

    Could it be Multibyte string functions? Could that return false for if ( have_posts() ) ?

    Thanks for any ideas

    Not having the multibyte string functions shouldn’t stop Relevanssi from indexing umlauted alphabet. It just may cause problems in for example excerpt-building –?you may for example see trash characters if a non-multibyte string function cuts the string in the middle of a multibyte character.

    I don’t know how the missing multibyte functions affect the search —?I’ve never had a server without them, so I haven’t been able to test. Can you get the multibyte string functions installed? Since you use German alphabet, you’d benefit from them.

    If you can and want to debug this further, I can give you some pointers where to look at.

    I’ll try to get multibyte characters installed first. Let’s see if this fixes things.
