UnicodeEncodeError: 'charmap' codec can't encode character '\u202f' in position 54: character maps to <undefined> encoding with 'cp437' codec failed

[codejoey]

Tried to view an export zip via Mac terminal.

Ran into this error which halts it. Any ideas?

I managed to get something working by first extracting the archive in a new directory and then point the viewer to that. I know, workaround, but haven't debugged it. It was trying to decore an utf-8 string using cp437.

I ran into the same error. Did you happen to export from slackdump? It might be that slackdump is using UTF-8 instead of cp437 for the zip file.

I had this problem too, it was complaining about files with áéíóú characters in them. My temporay solution was to comment this line and suddenly it worked fine:

# info.filename = info.filename.encode("cp437").decode("utf-8")

slack-export-viewer/slackviewer/archive.py

Line 74 in 0e82996

info.filename = info.filename.encode("cp437").decode("utf-8")

I don't know why that encoding conversion is there in the first place though, I feel that it shouldn't be necessary and it creates problems for people that don't have English as their default language. 🤔

same problem

[conjon42]

Same problem, using an archive from slackdump on MacOS.

[laviddichterman]

+1. From slackdump on MacOS installed with homebrew.

@aalkz that change was added in this PR: #166 - if other people can confirm that reverting this change unblocks them then this change can be reverted (or perhaps added as an option in the program to enable or not).

I had the same problem, comment out the line unblocked me. However, it won't be able to show the direct messages. and I don't know if this is related to this line of code or a unrelated known problem.

it won't be able to show the direct messages

There is a PR to revert the old default: #218

In the mean time, with the latest version you can use the command line flag --show-dms

in my case this was due to user names with accented characters like é etc.
I unzipped the file, opened the users.json and replaced all accented characters there. Zipped it again and generating with --html-only worked again.

I encountered the same issue with Korean as well. Commenting out the line at this location resolved the problem for me.
