Description (last modified by SergeyBiryukov)

On IIS 7 installs, there is a known issue in the FastCGI module in how it handles the REQUEST_URI server variable for non-ascii characters.

"IIS team is planning to provide an update for it soon." ... that was 18 months ago.


Please include this workaround in the core's wp-config.php file:

if (isset($_SERVER['UNENCODED_URL']))

Thank you!

There was a patch released for IIS FastCGI module that fixes this. See the details here: http://ruslany.net/2010/03/important-update-for-iis-7-0-fastcgi-module/

Thanks. From what I gather, the patch is installed in SP1 so Windows Update takes care of that, and it was on my system already.

What may be worth pointing out to others is the need to manually run the the command listed in the KB article to enable the UTF8 handling so all works properly:

reg add HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\w3svc\Parameters /v FastCGIUtf8ServerVariables /t REG_MULTI_SZ /d REQUEST_URI\0PATH_INFO
