Python UnicodeEncodeError: codec cannot encode character

I created an executable from my python script (checkData.py)

I am trying to pass string data that includes locale characters to this exe file from another python script something like below:

...
dataPath = easygui.fileopenbox(msg, title)
p= subprocess.Popen(["checkData.exe",  dataPath], stdout = subprocess.PIPE )

      

        
        
        
      

    

When I type dataPath

from the calling script, I can see the locale characters. When I tried to print the line passed to the exe file, I got an error.

...
parser = ArgumentParser()
parser.add_argument("directory", action="store")
args = parser.parse_args()

print(args.directory)

      

        
        
        
      

    

Here is my error message:

C:\script\build\exe.win32-3.2>checkSi‌​mTestData.exe

When I run below command:

sys.stdout.encoding

      

        
        
        
      

    

I got "cp1254"

could you help me?
