indexing rich data from directory using solarium

[kostali hassan]

HOW I can indexing from solarium rich data(msword and pdf files) from a
dirctory who contient many files, MY config is

$config = array(
         "endpoint" => array("localhost" => array("host"=>"127.0.0.1",
         "port"=>"8983", "path"=>"/solr", "core"=>"demo",)
        ) );

I try this code:

$dir = new Folder($dossier);
$files = $dir->find('.*\.*');
foreach ($files as $file) {
$file = new File($dir->pwd() . DS . $file);

$update = $client->createUpdate();

$query = $client->createExtract();
$query->setFile($file->pwd());
$query->setCommit(true);
$query->setOmitHeader(false);
$doc = $query->createDocument();
$doc->id =$file->pwd();
$doc->name = $file->name;
$doc->title = $file->name();
$query->setDocument($doc);

$result = $client->extract($query);
}

When i execute it i get this ERROR:

org.apache.solr.common.SolrException: URLDecoder: Invalid character
encoding detected after position 79 of query string / form data (while
parsing as UTF-8)
