This is a common class of bug not specific to FreeBSD. Without an encoding specified for the open() method, it relies on the default system encoding(non-deterministic), which may not be UTF8 (in this case ascii) [1]. The solution is to specify the encoding to be used, so as not to be platform/system dependent. Examples: * https://bugs.launchpad.net/pbr/+bug/1704472 * https://github.com/mozilla/unicode-slugify/issues/16 * https://bitbucket.org/genomeinformatics/simlord/issues/1/error-when-installing-simlord-ascii-codec * https://github.com/morepath/morepath/issues/286 * https://github.com/chaoss/grimoirelab-perceval/issues/32 * https://github.com/rbarrois/python-semanticversion/issues/13 * Many others.

Several ports had this problem that was patched. Testcase: math/py-cyipopt How to reproduce: 1. Remove the patch files/patch-ipopt_version.py 2. Run: make FLAVOR=py36 Observe this error: ===> Configuring for py36-cyipopt-0.1.8 Traceback (most recent call last): File "<string>", line 1, in <module> File "setup.py", line 28, in <module> exec(open('ipopt/version.py').read()) File "/usr/local/lib/python3.6/encodings/ascii.py", line 26, in decode return codecs.ascii_decode(input, self.errors)[0] UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 199: ordinal not in range(128) The file setup.py is marked as utf-8. The file ipopt/version.py that it reads is also marked as utf-8. Python should be using the utf-8 codec to read this file and not fail like this. This doesn't happen with python-2.7.
