Fails with pythin3: 'ascii' codec can't decode byte 0xc3

[yurivict]

Traceback (most recent call last):

What version of cyipopt is this from?

[yurivict]

0.1.8

[yurivict]

The offending file: ipopt/version.py

[moorepants]

I need more information that you are providing. Can you try to open the file and read the contents and report the error here? The file does have a unicode character in it so I'm not sure why ascii decoding is being used. I can't reproduce this with Python 3.6 on ubuntu, the file opens fine. What OS are you using?

I had to apply this patch:

I'd prefer to keep Matthais name spelled correctly in the files and find our why this fails on your machine. Python 3.6 should be able to read unicode just fine.

[yurivict]

It's not on my machine. This is in the FreeBSD port. This happened before, but I never understood why this happens.

[moorepants]

Are you packaging it for FreeBSD or something? If so, then just apply the patch downstream. Otherwise, I am not sure if enough details are provided. I am not familiar with FreeBSD and don't have an easy way to reproduce this. Maybe the Python on FreeBSD has an issue?

[yurivict]

I am investigating, and asked FreeBSD this question: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=231650

[moorepants]

@yurivict Can you test #35 ? Maybe that simple fix works.

[yurivict]

As it turned out, the open call defaults to ASCII.
You need to specify the encoding: open(filename, encoding="utf-8").

[yurivict]

@moorepants This patch fixes the problem.

[moorepants]

There is now a 0.1.9 on pypi with this fix. Thanks for the help.
