I want the shell output as seen in the final html to be a reasonable approximation of the shell output a user would see if the command were run in something like xterm.  Based on feedback from people in the Org community, I thought there might be a way to toggle off certain characters.

I understand.  Somehow, the output of Guix CLI is dynamic where Org
babel captures static text (the last output).  Therefore, maybe you
could demo using Gifs or something in this flavor.

You also raise a good point, however, that the characters originate upstream. Anything Guix might do would be a work around and work arounds are probably best handled in Emacs.

Some special characters (as coloring) are from Guix and it should be
possible to turn them off.  However, others are from progress-bars;
some from Guix itselfs, other from guile-git.  Therefore, I am not
sure what you are asking, I mean, are you asking to be able to turn
off all the progress-bars?

Yes, my example was just... an example.  I am sure one could come with
more complex filters for formatting adequately.
