Please read this:

I had a look at the two files - the fonts have 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.
