Gnuplot PDF Terminal Exhibits Font Issues on Mac
For Homebrew, I changed the pango formula to stick to version 1.43
Until it gets fixed, this should solve the problem:
brew uninstall --ignore-dependencies pango
brew install iltommi/brews/pango
This will install this formula: https://github.com/iltommi/homebrew-brews/blob/master/pango.rb in which I replaced the v1.44 to 1.43
As of Aug. 24, 2020, the version of Pango on homebrew is 1.46.1 and this bug seems to have been fixed. Doing a clean installation of Gnuplot and Pango via homebrew should solve this problem.
Installing newer version Pango 1.45.5 seems to resolves the issue as well, please confirm:
brew uninstall --ignore-dependencies pango
brew install dersimn/craft/pango
