Those symbols are probably coming from a special font for which there isn't a mapping to Unicode. Without such a mapping PDFBox can't tell what character to output for each symbol. You can try to inspect the PDF document for the font that's used, and look for existing CMap files for that font. In the worst case you may need to construct such a character map yourself to teach PDFBox how to interpret the symbols used in your document. BR, Jukka Zitting
