can’t see Thumbnails in Media-selector

howdy,

Here is a problem with showing thumbnails after click the “Media-selector” button.
When I create a folder name “*there is two japanese character using unicode*”, and put some images into the folder, then go to the post editor page to select them, the problem just happen.

I grep the resource and found while using unicode character, the “subfield” variable will contain a part of the seleted attachment image name.

[1]=>
object(stdClass)#10053 (6) {
  ["post_title"]=>
  string(8) "capybara"
  ["subfolder"]=>
  string(16) "販促物/capyba"

but while creating folder with a totally alphabets and numeric name that won’t be happen. just report this issue if someone else have the same problem.
