[MortenZ]

Python 3.4 introduced a problem with use of

# -- coding: ASCII --

so when running on Windows, the EOL must be Windows type, and else an error is generated.

See trials below:

C:\>Python34\python.exe hello_unix.py
File "hello_unix.py", line 3
II -*-
^
SyntaxError: invalid syntax

Hmm. This might be related to bpo-20731?

[MortenZ]

Yes, sounds like a duplicate of http://bugs.python.org/issue20731

But with the fix applied 2014-03-01, is the bug expected to be in 3.4 released 2014-03-17 ?

[Arfrever]

Fix was not cherry-picked to 3.4.0.
Fix will be in 3.4.1.
