I have a problem:
In "email" module when I wanted to download an attach file,especially a .csv file , I have a problem. After that I click on the link, a window appear and I can save it for downloading but because I used UTF-8 characters, instead of characters in my files , characters didn't display in right way , it means that some bad characters are in my .csv file. what do I do?????????????
I attached an image and on it determined that which attachment I said, Also I determined a box with a red border(number1).
Can any one tell me , where is the php code that related to this attachment.
Please help me!!!!!!!!
