Closed dan-zilla closed 2 years ago

I have converted a psf file to ascii using the psf utility as described in the readme. However, I am still not able to read the file. The error I am getting is below. I am attaching the psf file as well. psf.zip

KenKundert commented 2 years ago

I think I have fixed the issue. Can you pull the latest version (1.3.1) from github and try it.

dan-zilla commented 2 years ago

It works for me now. Thanks for providing and supporting this tool!

KenKundert commented 2 years ago

I have updated pypi. Thanks for your help.
