Apparently triggered in this case by a path name with exotic characters in settings.

I believe I fixed this. The bug was that the utf-8 encoding was not specified when reading the preferences file.

Please download and test the next release candidate, with a build date of 2020-05-14 or newer, and confirm if the bug is fixed or not.

Thank you. -- Greg

[Greg Couch]

No response. Assume it's been fixed.
