Dear list

On Fedora 31 the pango library has recently updated to version >= 1.44
and in doing so has switched to using the HarfBuzz library (from
FreeType) and dropped Adobe Type 1 font support. This causes problems
with plotmath as all bar one of the glyphs doesn't render (see
attached PNG image if it makes it through the list filters - if not I
have shared a copy via my google drive:

I'm not the only person who has come across this, e.g.
https://stackoverflow.com/q/60656445/429846 and the resulting reported
bug on the RedHat Bugzilla:

Beyond switching to  `type = 'Xlib'`, has anyone worked around this
issue on a Fedora 31 or later system?

Thanks in advance
