Re: PDFMergerUtility in PdfBox 2.0.0 fails to embed font

Hi,

I haven't tested your code, because I believe it is a known problem:
https://issues.apache.org/jira/browse/PDFBOX-3243

see workaround there. Btw the title is incorrect, you're using a TT 
font, not a Type1 font.

When opening such a file with Adobe it shows the error message "Cannot find or create the font 'NotoSans'.  Some characters may not display or print correctly" and every character displays as a black dot.

If you run the code as-is, you'll get a PDF with the missing font.  If you run it again after uncommenting the line "document.save(new ByteArrayOutputStream());"  then the PDF contains the font and works properly.
