UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 68: ordinal not in range(128)

Hello, I am not sure that my way to use HAROS is good, but :

1. I put it directly to my package folder (along with src) cloned folder make-haros-easy and follow the instruction inside
2. I create project folder with some yaml file and launch

`
(harosenv) hugh@hugh-Legion-Y540-15IRH[ecm30] ~/catkin_ws/src/telemetry/qr_telemetry(master) $ ls
CMakeLists.txt launch make-haros-easy package.xml projects README.MD src
(harosenv) hugh@hugh-Legion-Y540-15IRH[ecm30] ~/catkin_ws/src/telemetry/qr_telemetry(master) $ haros full -s 0.0.0.0:8080 -p projects/minimal.yaml

Using Docker, this shell command also gives an error

Hello, Artem. Thanks for reporting the error!

Placing HAROS within a package might cause trouble (but not the error you are seeing).
I think it will try to scan its own files, as if it was part of the package. I might have to add a clause for it to ignore itself in the future.

I see that you have a virtual environment within make-haros-easy. Just to be sure, try cutting and pasting the top level make-haros-easy directory outside any packages. Maybe within the workspace, but outside of src, for example.

As for the error, I think it is trying to open a file with non-ASCII characters in it in ASCII mode. It should be easy to fix, if that is the case. I will try to get to it tomorrow, or Monday at the latest.

@melnarte I have published a new version that should avoid this error.
Please update to v3.10.16 and let me know.

If you installed via pip, you can run

pip install --upgrade haros
