    How would I do that? It seems to be impossible for "Courier" because this
    is a built-in font "and all viewers can display them", as stated at https://durak.org/sean/pubs/software/php-7.0.0/haru.builtin.fonts.html
    So it won't make much sense to embed Courier into the PDF anyway?!

    Nobody said anything about embedding Courier. You said the problem
    happened when the "Nimbus" font was used, so it was suggested you
    embed the "Nimbus" font.

    But I don't want to use / embed the Nimbus font at all!

    libharu is called by HaruDoc::getFont('Courier', 'WinAnsiEncoding')

    This *does* work - the font *is* Courier when you look at the PDF.

    But -
    - until ghostscript 9.55, in the PDF font properties, the font
    was correctly named "Courier" so that every PDF reader could
    display it;
    - from ghostscript 9.56, in the PDF font properties, the font
    is named "Nimbus" instead of "Courier", and some PDF readers
    have problems to display.

    The only "Nimbus reference" I have found is a line in the file /usr/share/ghostscript/9.56.1/Resource/Init/Fontmap.GS which reads

    /Courier /NimbusMonoPS-Regular ;

    but this line is the same in gs 9.55 and 9.56. So I don't understand
    what/why has changed here.

    BTW, I now have tried to embed truetype fonts. Seems to work
    (although the character outline is thinner, overall more "pale").
    File size increases from 29K to 121K - would be OK for me...
