If the "crash" is the following message, this issue is a duplicate of  #6058.

PS D:\jm> c:\python31\python.exe 
Fatal Python error: Py_Initialize: can't initialize sys standard 
streams 
LookupError: unknown encoding: cp65001

It is not a crash: Python has no codec for the code page 65001, that's all. I closed #6058 because cp65001 cannot be set as an alias to utf-8. Anyway, use 65001 as console encoding is not a good idea. I close this issue: see #1602 for more information.
