Q: saving error... in python2.0 GUI tool

[Hwanjo Yu]

Hi,
When I try to save a source file after I modify it in IDLE (Python GUI), it
generates the following error.
What is wrong?

>>> Exception in Tkinter callback
Traceback (most recent call last):
  File "c:\program files\python20\lib\lib-tk\Tkinter.py", line 1287, in
__call__
    return apply(self.func, args)
  File "C:\PROGRA~1\Python20\Tools\idle\IOBinding.py", line 128, in save
    if self.writefile(self.filename):
  File "C:\PROGRA~1\Python20\Tools\idle\IOBinding.py", line 154, in
writefile
    f.write(chars)
UnicodeError: ASCII encoding error: ordinal not in range(128)
