When i upload a image attribute in a object with a chinese name, the image is created with a name strange in system. But in database, the name is correct in chinese.
So it can't find the image in BO because the name is not correct in system.

I look in the file kernel/classes/datatypes/ezimage/ezimagealiashandler.php

function imageName( $contentObjectAttribute, $contentVersion, $language = false )
{
   ...
$objectName = $contentVersion->versionName( $language );
   ...
}

The image name is the object name (chinese charset)

i tested in the file lib/ezutils/classes/ezhttpfile.php

if ( !move_uploaded_file( $this->Filename, $dest_name ) )

the $dest_name is in chinese. But after the file created, the name is changed like a codage strange.

My solution : give the image name by obj_id and obj_version
i changed the code in kernel/classes/datatypes/ezimage/ezimagealiashandler.php

//for function imageName and imageNameByNode
//added by LIU Bin for the chinese image name
        if ( is_object( $contentObjectAttribute ) ) 
        {
        	$objectName = $contentObjectAttribute->attribute('id')."_".$contentObjectAttribute->attribute('version');      
        }
        else
        {
            $objectName = $contentObjectAttribute['id']."_".$contentObjectAttribute['version'];
        }

Somebody has a better solution ??? Thanks
