File Upload Library and special characters

Hi, I just re-read everything. And your Javascript looks okay. The file name aren't submitted in the URL.
Can you find the PHP code for the upload part?

Do you get the correct name here in your HTML after upload?
<input data-name="'+data.response.file_name_unreplaced+'" type="hidden" value="'+data.response.file_name+'" name="userfile[]">

Try and delete this part:

Code:

slugCallback: function(filename) {
return filename.replace('(', '_').replace(']', '_').toLowerCase();
}
