Confusing font error: (UnknownFont) is not a known font.
i created a theme which uses extends and font catalog merge and some company specific DIN fonts wich creates a PDF without errors being a part of docToolchain gradle based automation for building on mac 10.15.7 using asciidoctorj 1.6 and asciidoctorj-pdf 1.5.3:
But as soon as i define these fonts for base by adding:
I get the confusing font error: (UnknownFont) is not a known font.
As this font is not added but already used in the upper version, i presume this is an underlying error of a different type and the shown error is misleading. My assumption is that maybe there is some incompatiblity between settings in the default themes and the company fonts... but i currently have no clue how to dig deeper by enabling more detailed output of asciidoctor-pdf converter being embedded into docToolchain. How would you debug this?
Do you have seen similar errors already?
My next ideas would be to replay this behaviour with
1. some other DIN like fonts to exclude the font itself being the problem
2. local asciidoctor and ascidoctor-pdf installation on mac to be able to exclude docToolchain as a source.
but of course i would prefer if there is a less time consuming variant to debug with the existing environment.
