choice is /usr/local/bin/audacity, which is the correct path for
audacity on my system. As far as I can see, that string has no hidden bytes.
Invoking /usr/local/bin/audacity from the command line launches audacity
and so does choosing with dmenu_run. which -a audacity shows only that
item.
Maybe I need to isolate the function call and start stripping out
parameters. I should have time to do that later today.
Thanks
