Description

After migration of our App from pdfbox 1.8 to 2.0, we noticed a regression: 4 lines of texts are disappeared. Those are the texts followed by black bullet (3 lines) and also "OVERALL" word which is placed above in table.

Problematic PDF attached - highlight19.pdf_page1.pdf

Also, attached the result of DrawPrintTextLocations example -
highlight19.pdf_page1-marked-1.png

Notice, that unicodes, red and blue boxes missing for problematic text. The main problem that these glyphs are absent in textPositions parameter which is passed to writeString function, line #275. In the 1.8 version these characters ARE present, so their positions along with their char codes could be extracted fine in our App.

Also, attached picture of regression in our App - regression_in_blue.png. Here, blue boxes drawn where text WAS present and disappeared afterwards. (The purple boxes are OK and should be ignored.)
