[issue37570] `distutils.util.byte_compile` fails indirect byte compiling with non-ASCII full-path.

Thanks, but Those cannot resolve this issue.

This is install time problem. In other words, whatever the default encoding is, 
even some users change it, `distutils.util.byte_compile` must always succeed. 

There's no relation between using non-ASCII path and the default encoding. 
No logically reason to fail.

FYI, PEP597 is created to avoid these issues (i think), target Python 3.9.

... and please check "batch.diff" (Oops, that's typo of 'patch'). I just added 
"encoding" parameter to calling open() function, and added the temp file to 
'utf-8' code declaration. This bug could happen where the default encoding of 
open() function is not utf-8(may not only Windows).

All 'The byte compiling test seems succeeded.' when i tested your script on 
ubuntu 18.04 on latest 3.7.4rc2+, 3.8.0b1+ and 3.9.0a0.

What are the exact python versions and the OS version you see the issue?

Here's test code.

Note: I marked just Python 3.8 and 3.7 I tested, but maybe all versions.

[issue37570] `distutils.util.byte_compile` fails indirect byte compiling with non-ASCII full-path.

[Suzumizaki]

New submission from Suzumizaki :

`distutils.util.byte_compile` fails _indirect_ byte compiling when the
full-path of the .py file contains non-ASCII characters.

Because there is the project (cx_Freeze) which directly uses
`distutils.util.byte_compile`, the problem would happen while installing it
under the non-ASCII path.

Fortunately, it is easy to fix.
 
Ofcourse, the files included in external libraries should be named ASCII only,
but `distutils.util.byte_compile` makes and uses full path of them. I learned
many of libraries uses setuptools instead of distutils, but please consider
the following situations:

1) The case that venv creates the virtual environment under or with
   non-ASCII named folder.
2) And special cases of 1), on Windows, the name of end-users OFTEN be
   composed with non-ASCII characters, this means including theirs
   Documents, Desktop, or Downloads etc.

The more they are not professional,they make easily the situation above.
