HTTP Error 406 - Not acceptable on non-latin search

Hello!

 

All works fine except when I try to make a search in non-latin characters. In that case no page is shown and the header showes 406 error (which in English version browsers reads as "HTTP Error 406 - Not acceptable"

 

The file from an URL giving the error is advanced_search_result.php v 1.72 2003/06/23 06:50:11 project3000

see the code here:

 $content = CONTENT_ADVANCED_SEARCH_RESULT;

 include (bts_select('main', $content_template)); // BTSv1.5

 require(DIR_WS_INCLUDES . 'application_bottom.php');
?>

 

I also tried to search the same non-latin strings on other OsCommerce sites and all went well.

 

And more: when I copy-paste an URL-encoded search string produced by other site to mine - it worked fine as well.

 

So my guess is that the problem might be in wrong url-encoding (or other type of encoding) on my OSC.

 

On the other hand when I copy-paste it vice-versa (from my wrong string to the other sample OSC site) -- the script works anyway.

 

Who can help me?

Hosting support has fixed it somehow.

 

So those facing the same error should ask hosting support first.
