PDFTextStripper.getText misses some characters from a PDF file

[jamiehiggins]

When attempting to extract text from the attached simple PDF file there are some characters missing within the text.

To reproduce the problem simply call pdfStripper.getText() on the attached pdf file (Problematic.pdf)

The text is mostly returned ok, however the following issues are present in the returned text:

making time to reflect and review your -> making time to reect and review your
If you find it easier -> If you nd it easier

PdfBox-Android version: [e.g. 2.0.27.0]
It happens on all versions of Android SDK (I have tried several)

This is an unsolved problem
https://issues.apache.org/jira/browse/PDFBOX-3248

In this file, the /ToUnicode file maps ligatures to 0 and uses the /ActualText feature in the content stream which PDFBox doesn't support.
