You didn't tell us your OS.  That is a binary file, and from 

     mode: character.  The mode with which to write the file. Useful
           values are ‘"w"’, ‘"wb"’ (binary), ‘"a"’ (append) and ‘"ab"’.
           Only used for the ‘"internal"’ method.

Only on Windows are the binary modes different, so it looks like you
forgot mode="wb".
