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

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, using an archive from slackdump on MacOS.
