Explicit set utf-8 headers for file operations (#157)

File operations need to have utf-8 headers otherwise special allowed
characters will break the file action as they will encoded to ascii per
default.

If you have files with äöü etc. you will get an ascii encoding error
cause of the reference in the Header.

This fixes this issue

 * Set Headers to encode to UTF-8 on file operations
