UnicodeDecodeError preventing usage

[theswampire]

I just encountered this exception on a fresh install of python-umonitor. autorandr was previously installed. I have not saved any profiles yet and it prevents from doing so.
On Archcraft, installed using yay.
Edit: tried using python setup.py install but no difference.

Same issue on Archlinux.
Was installed and working previously. Broke after upgrading packages at some point.

[xxx@arch ~]$ umonitor -a

Command will work correctly sometimes but will fail other times.
This was within a few seconds.

I just rebuilt screen.c.

Try the newest version and see if the error still happens.

The latest rebuild fixed the issue on my distro.

Both installing from AUR and from git function now without the UnicodeDecodeError.
