[BUG] UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe2

Someone reported this to me in person:

When starting sml-sync, before the difference screen is shown, the following bug came up:


Apparently, after attempting to sync again, this error went away, although it's unclear to me whether that was after trying to sync a different folder (they may have tried to sync their home folder first).

I wonder if this is because their home folder must have had a huge number of files and there may have been some truncation of the file list?

It's hard to know what's going on without being able to reproduce it, but I thought I'd raise it to document it here
