First, a call to abort() is not a GPF: it's not an interrupt from the kernel or
the OS, it's just an explicit (albeit brutal) way to exit from an application.
There is no potential back door here.
Then, the Fatal Python error: line
STINNER Victor victor.stin...@haypocalc.com added the comment:
Finally, the fix you suggest would be applicable if python
used WriteConsole or WriteFile... but it does not! It uses
the write() function, which probably calls WriteConsole
or WriteFile at some point, but does not take unicode

Victor, thanks for replying and I've had a quick read of everything that went
on for issue #1602. I think there's some misunderstanding in what I'm saying
here. Maybe this will help clear up what I'm saying...

All I'm trying to do is run different versions of Python on the same machine
from the command line.
Some code inside Python now break if Python 3.1 is started with Code Page
65001.
Yes, this issue can be seen as a regression
STINNER Victor victor.stin...@haypocalc.com added the comment:
You can use PYTHONIOENCODING=utf-8. Code page 65001 is not exactly like
Python UTF-8 codec: see issue #6058.
Using issue #12281, it may be possible to implement a cp65001 codec.
See also issue #1602 for the Windows console.
Why
Bruce Ferris bferri...@bferris.co.uk added the comment:
I use code page 65001 because 1) it displays the UTF-8 characters in my text
files with echo filename on the command line, and 2) that's Microsoft's
official (whatever that means) code page for UTF-8, and 3) it works in
cmd.exe.
Setting
R. David Murray rdmur...@bitdance.com added the comment:
In this case it is not a potential security hole, since in fact the GPF comes
from Python explicitly calling Abort because of a situation it can't handle, as
indicated by the error message from Python. (If it were a true segfault-like
STINNER Victor victor.stin...@haypocalc.com added the comment:
Python shouldn't GPF for ANY reason if it can be easily fixed
Code page 65001 issue cannot be easily fixed. Did you read the history of
the issue #6058? It took one year and a half to decide that cp65001 cannot be
set as an alias
Bruce Ferris bferri...@bferris.co.uk added the comment:
I disagree with the it's not really a GPF since it calls Abort.
Consider the following cmd.exe session...

R. David Murray rdmur...@bitdance.com added the comment:
If you read what I wrote, I did not say that it wasn't a GPF. I said that an
Abort is different from writing into or reading from memory incorrectly (which
is what leads to security holes).
We don't have many Windows developers active
