I already had a problem similar to this one, this means that you have a long file name with non-latin characters inside the directory, and the width I calculate is wrong.

Can you paste here the name of the file that makes rnr crash, please?

If you're not sure which one is the file that makes rnr crash, you can create a temporary directory, and copy one file at a time inside the temporary directory, and then try to start rnr from that temporary directory, until you find the file that makes rnr crash.

The above errors was on my home directory.
I created a directory in /tmp called test and created a blank file called hello.txt

with file inside the directory or without it the errors are same.

This problem is harder than I imagined, if it's not related to the file names, then I don't know what it is.
From the error it looks like urwid wrongly calculates a width of 3 for the box drawing character U+2500 (b'\xe2\x94\x80' is U+2500 encoded in UTF-8).

My suspicion now is that you don't have utf-8 as the default character encoding.
Can you paste me the output of the command:

python3 -c 'import sys; print(sys.getdefaultencoding())'

Also, try running rnr with this command:

env LC_ALL=it_IT.UTF-8 rnr

and tell me if it works.

I don't get it, you have utf-8 as the default encoding (as it should be), and treating that string as utf-8 gives a width of 1, not 3.
I have no idea of why this happens.

I'm suspecting that this has something to do with your specific customizations, I don't know if you have customized Python3 in some way (for example setting PYTHONPATH or similar environment variables, or you're using a sitecustomize.py file or similar).

I cannot reproduce your problem, so I'm afraid I cannot help you.

[vnc2017]

no problem @bugnano. I have not done any changes to PYTHONPATH or sitecustomize.py. Thanks for troubleshooting.
