Crash when saving PDF with Japanese text

[williamahartman]

Thanks for working this application! the OCR process has been flawless and the output is much easier to validate than using the tesseract CLI. Unfortunately I'm seeing crashes when trying to save a PDF with Japanese text. The OCR parts all work great and I can save as .html or .odt with no problems. I can also export PDFs of English text using the default export settings without any problems.

If I try to export a PDF with Japanese text with the default export settings, the program silently exits, but this error gets printed if I run from the console.

** (gimagereader-gtk:328452): ERROR **: 12:29:43.119: 
unhandled exception (type std::exception) in signal handler:
what: PdfErrorCode::InvalidFontData, The font data is invalid.
Callstack:t#0 Error Source: main/PdfEncoding.cpp(82), Information: The provided string can't be converted to CID encoding

If I instead set the font in the pdf export settings to a CJK one ("Noto Sans Mono CJK JP" in my case), I get an error window with some debugging information, which I've included below.
