Binary bin file can not be installed in latest setuptools

[yaoking]

Recently, I upgrade my setuptools from 4.0.1 to 20.2.2, I found the binary bin file in script can not be installed.
There will be decode error: UnicodeDecodeError: 'utf8' codec can't decode byte 0xb0 in position 24: invalid start byte
It seems open('rb') is used in 4.0.1, but io.open('r') replace it in 20.2.2.
Could you help check this issue? Thanks!

You'll have to provide more information, perhaps a traceback or similar. io.open('r') doesn't appear anywhere in the setuptools codebase, so I assume you must be paraphrasing.

I do see this section where a script is opened as text. Is that where the error occurs?

Looking at #218, it seems that this is a duplicate of #210. Setuptools 4.0 and 4.0.1 were the only versions that had a fix for this issue, but because the fix caused regressions in other systems, it had to be rolled back in 5.0.

with io.open(script_path) as strm:
script_text = strm.read()
I think the default open mode is 'r', but my script is binary file.
scripts=['script/cli_aatrace_utility_debian']
Thanks!
