Is there any way to export plots as pdfs correctly on Ubuntu?

An example of the problem:

ListPlot[{{1, 1}, {2, 2}}, AxesLabel -> {"\[CapitalDelta]", "#"}, 
 PlotLabel -> 
  "characters don't export well: \[Gamma] \!\(\*SubscriptBox[\(\
\[CapitalOmega]\), \(mn\)]\)."]
Export["exampleExportBugPDF.pdf", %];


enter image description here

Is there any work-around? If that is not possible, what is the closest way to export plots such that they looked good when zoomed in.

There are previous questions on this subject such as Problem with special characters when exporting to pdf but they were apparently fixed in 12.2. Now in 13.2 I have same symptoms.

Other suggestions such as below don't change anything:

  PrivateFontOptions -> {"OperatorSubstitution" -> False}];

  StyleDefinitions -> 
   Notebook[{Cell[StyleData[StyleDefinitions -> "Default.nb"]], 
      PrivateFontOptions -> {"OperatorSubstitution" -> False}]}]];

Exporting as .eps has the same artifacts.

  • $\begingroup$ There is a recent similar question on this topic (with one hackery solution). Also, this looks like a very clear bug, and I strongly suggest you report it to Wolfram Technical Support. $\endgroup$

  • $\begingroup$ @Domen, yes I was actually thinking that a performing the export on the Cloud might help. I have a slightly different applications though (single plot vs document) so I don't think this is a duplicate. Also I prefer programmatic solutions if possible. I imagine it might be possible to do the export on the cloud programmatically but I am not that familiar with those functionalities. $\endgroup$
