Actually, I just tried on my own Mac and it does show the problem when I am using the Hershey font (Ferret's font, which is the default).
If you use a system font ("SET TEXT /FONT=Arial" for example), then there is no problem.
Thank you for the information. I'll use that in my ~/.ferret .
FYI - I am using Mojave OS, Python3.8, the latest PyFerret code from GitHub built using homebrew libraries.
Mine is macOS Catalina. (All upgrades are installed as they come in.) I don't know exactly which python version the miniconda package uses, but . . .
$ brew info python
python: stable 3.7.7 (bottled), HEAD
. . .
Python has been installed as
/usr/local/bin/python3
$ brew cask info miniconda
miniconda: 4.7.12 (auto_updates)
. . .
