exporting figure as .pdf causes axis title to display the Angstrom character incorrectly

Hi all,

I have produced a plot and have labelled the axes as such:

xlabel('q (Å^{-1})', 'FontSize', 18)
ylabel('F(q) (barns sr ^{-1} atom^{-1})', 'FontSize', 18)

I have then exported the plot as a .pdf file with the following line:

exportgraphics(gcf,'example.pdf','ContentType','vector')

These steps have produced the image below. As you can see the x-axis is displayed incorrectly, featuring a "#" in place of the "Å" symbol. I have tried exporting as an .eps file and that works fine, but unfortunately I need a .pdf file.

Any help is greatly appreciated!

What version of MATLAB are you using?

Hi Chris,

Sorry for the late reply. I am using MATLAB version R2021a Update 6 on MAC.

@Cris LaPierre Problem fixed by updating to R2023b.

It seems to work ok if you use ContentType image. I'd mess with the resolution if you go this route so you get a better looking image.

This looks like it might be a bug with exportgraphics. I'd suggest reporting it to MathWorks; they might have a better answer for you.

exportgraphics(gcf,'example.pdf','ContentType','image')

I solved this problem by selecting another Font. Just adding:

set(gca,'FontName','Arial')

and still using

exportgraphics(gcf, 'example.pdf', 'ContentType','vector')

did it for me!
