-----------------------------------------
Please read this:
https://pdfbox.apache.org/2.0/faq.html#notext
I had a look at the two files - there's no ToUnicode stream so PDFBox can't
know. (That's also why you're getting so many warning messages).
You have to understand that what you see is just pictures of vector drawings (=
glyphs). They are missing the unicode assignment. This is possibly done on
purpose, to prevent text extraction. All that could be done is OCR. Apache TIKA
has an option for this.
