Glitch signs introduced by illustrator when opening a plot created by R
Hi everyone,
I mainly use Illustrators to manually edit plots/figures created by R (a statistical programming tool). R creates PDFs which can (normally) be opened and edited using Illustrator.
However, I recently encountered a strange bug. My plots look just fine when I open the PDFs using Acrobat Reader, but they contain glitch signs instead of points when I open them using Illustrator 2023.
I am attaching a (zoomed in) picture showing these symbols. If anyone can help, that would be very appreciated :).

The problem got resolved with changing the font manually in the imported PDF. However, it does not explain the problem completely. Please comment if you have new information on this.

Hi again Egor,
Sorry for not clarifying. I changed the font directly in Illustrator, pressing ctrl+A to select all objects and then changing the font. The points then magically appeared normal.
There must be a more permanent fix to this bug, perhaps by reinstalling the "Myriad pro" font in Illustrator, but I haven't had time to dig into this.

Samuel, glad it got sorted out, but where did you changed the font exactly? In the imported PDF or in the R app?

Hello Egor,
Thank you so much for chiming in. Your suggestion was really helpful. I confirm simply changing the font of the whole figure to Arial does the trick :).

For me both Acrobat Pro DC and Illustrator display the top portion of the graph like the attached image shows.
'Missing' symbol. However, if I grab these and change the font form 'Myriad Pro' (not sure if it got reduced to the default font or if this is what was intentionally assigned to these) to 'Arial', the same as numbers use, these get magically fixed to 'black circle' symbols (U+25CF) — which look hollow, since they have the black stroke and no fill.
So the problem is that for some reason Arial got dropped, and it feels like Acrobat Pro and Reader give different results... or it can be a machine-dependednt problem.
How often does it happen?
