Well, my problem is that _syscmd_file() fails with a non encodable filename on
Linux because the file program writes the filename to stdout, but os.popen() is
unable to parse it because the filename is not decodable from the filesystem
encoding (without surrogateescape).
I would like to add -b option just to avoid this encoding problem.
The bug:
---
$ cp /bin/ls $(echo -ne "ls-\x80")
$ ./python -c "import platform; platform.architecture(executable='ls-\uDC80')"
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/home/SHARE/SVN/py3k/Lib/platform.py", line 1059, in architecture
output = _syscmd_file(executable, '')
File "/home/SHARE/SVN/py3k/Lib/platform.py", line 1006, in _syscmd_file
output = f.read().strip()
File "/home/SHARE/SVN/py3k/Lib/codecs.py", line 300, in decode

UnicodeDecodeError: 'utf8' codec can't decode byte 0x80 in position 24: invalid
