UnicodeDecodeError

[bartschuller]

I got the same error on Windows using Python36, but not on Mac using Python 2.7. The reference in the stack trace to "cp1252.py" is suspicious because we don't want any platform-specific things happening to the nice UTF-8 files.

In my case there were no channels with strange characters in their names, but messages do have them.

With Python 3.6, I got rid of this error (probably caused by the characters æøå used by my Norwegian Slack team) by adding encoding="utf-8" to the relevant calls to open() in archive.py. I think this breaks compatibility with Python 2, but I haven't tested that. jonathangjertsen@fea797e

@BenneyP i have similar problem, and got workaround:
Slack recently added Your channels, your language feature that allow you to add channel in any languange. So if you have not latin characters in your room name you should exclude that channels from zip file (simply remove from them archive) and remove section with these channels from channels.json file.

Same issue on Windows 10 64bit Python36-64
Here is the only difference in the log:
UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 10274: character maps to <undefined>
Seems like "<undefined>" was messed up by markdown.

Does anyone have a sample json file they'd like to volunteer? Seems like we just need to use the correct encoding when json.loadsing the file (if indeed everyone here is having the same issue).
Should ideally be a relatively simple fix assuming that is the issue.

Hi @hfaran!
Thank you for your great job!
Please take a look at the file attached (hf.zip). It produces next error on Windows 10 x64:

I appreciate you fixing the bug.

@bartschuller Did you try this with Python 2.7 on Windows?

[bartschuller]

@MikeFoden Sorry, I didn't and it's not easy for me to try.

[hfaran]

Only took me about a year, but finally got around to running it on my Windows box and fixing the issues. Encoding issue should be fixed!
