Misrendering of non-embedded CID Fonts
Attached a file which doesn't properly render umlauts.
It should read testing umlauts ä ö ü ß testing
but you actually see four different chars for the umlauts (looks like an encoding issue).
I'm seeing the issue with: atril 1.24.0 as well as evince 40.4, both using poppler 20.09.0 (all from debian packages), which is why I guess it's a poppler issue?
The file renders correctly in mupdf and firefox.
When embedding the fonts in the pdf it renders correctly.
$ pdffonts umlauts.pdf
name type encoding emb sub uni object ID
------------------------------------ ----------------- ---------------- --- --- --- ---------
Arial CID TrueType Identity-H no no yes 3 0
$ pdffonts umlauts-embeddedfonts.pdf
name type encoding emb sub uni object ID
------------------------------------ ----------------- ---------------- --- --- --- ---------
Arial CID TrueType Identity-H yes no yes 3 0
