I'm running a drupal site on a windows 8 machine here at a drupal meetup in Bangkok and we just noticed that the file with Thai file name gets rewritten from คุณลิ่วจาก.jpg to %E0%B8%84%E0%B8%B8%E0%B8%93%E0%B8%A5%E0%B8%B4%E0%B9%88%E0%B8%A7%E0%B8%88%E0%B8%B2%E0%B8%81.jpg and the file cannot be used afterward.
The file is also saved in the file system as คุณลิ่วจาก.jpg

This happened when we uploaded the file through IMCE, using the upload button in the IMCE popup window

PHP can not handle utf-8 filenames on Windows. Use transliteration module.
