 * Hello,
 * I get the following error when navigating to the Updates section after upgrading
   to v3.8:
 * PHP Warning: json_encode(): Invalid UTF-8 sequence in argument in C:\inetpub\
   wwwroot\www.***.com\wp-includes\update.php on line 254
    PHP Warning: json_encode():
   Invalid UTF-8 sequence in argument in C:\inetpub\wwwroot\www.***.com\wp-includes\
   update.php on line 254
 * I’ve looked at that line of code but I’m not a programmer. It says:
 * ‘plugins’ => json_encode( $to_send ),
 * I’m running:
    Windows Server 2008, r2 PHP v5.3.23 (FastCGI) IIS 7.5
 * Can anyone help me resolve this?
