Also, please notice that when our App was based on 1.8, user could copy/paste this problematic 4 lines of text. But the text was corrupted, although most of characters readable, but in uppercase. In the same time, OVERALL word was completely broken. I'm printing these 4 lines below:

> Project: PDFBox
> Issue Type: Bug
> Components: Text extraction
> Reporter: Roman

> 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|https://apache.googlesource.com/pdfbox/+/trunk/examples/src/main/java/org/apache/pdfbox/examples/util/DrawPrintTextLocations.java] example -
> [highlight19.pdf_page1-marked-1.png|https://issues.apache.org/jira/secure/attachment/12856229/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.
