New submission from John Van Praag <j...@jvp247.com>:
The declaration errors='replace' works from within IDLE but not at the Windows
command line. I am attaching a program and text file that demonstrate the
problem. The error shows up at the Windows command line as follows:
C:\Users\John\Documents\Python\bug_reports\001>python -m read_my_file
aaaaaaa aaaaaaaaaaaaa aaaaaaaaaaaaaaa aaaaaaaaa
bbbbbbbbbbb bbbbbbbbbbbb bbbbbbbbbbbbbbbbbbb bbbbbbbbbbbb
Traceback (most recent call last):

UnicodeEncodeError: 'charmap' codec can't encode characters in position 10-11:

NOTE: It appears I can only attach 1 file to this report. So I am copying the
program here. The text file to read is attached.
