-----------------------------------
Summary: quotedbl causes NullPointerException
Key: PDFBOX-2951
URL: https://issues.apache.org/jira/browse/PDFBOX-2951
Project: PDFBox
Issue Type: Bug
Components: PDModel
Affects Versions: 2.0.0
Environment: Windows 10 64 bit
Reporter: Juergen Uhl
I have a pdf document using (besides others) the font CourierNewPS-BoldMT and
text with this font containing a double quote.
When calling PDFont.encode, this results in a NullPointerException due to the
following:
The font encoding is built using pdf /DIFFERENCES which overwrites the original
"quotedbl" at index 34 with an "A". The entries for quotedblbase/left/right are
left unchanged. As a result, the inverted font does not contain "quotedbl" as
key.
Within encode, the character code 34 gets assigned the name "quotedbl", which
is then not found in the inverse encoding (PDTrueTypeFont.encode -> int code =
inverted.get(name))
Right before this code line causing the NullPointerException, there is a check
whether ttf.hasGlyph("quotedbl") (which in this case is false) and, if not,
whether ttf.hasGlyph("uni0022") (which in this case is true); however, this has
no consequence for the continuation of the code, which then crashes, since
inverted.get("quotedbl") is null (which is assigned to an int).
I believe, this is a bug in PDFBox, but have no idea, whether the handling
within encode should be changed (maybe using the "else" part in case
ttf.hasGlyph("quotedbl") is false or whether code 34 should be assigned to
quotedblbase in the first place, or even something else.
I attached the file (Test.pdf) where the error occurs and a jar (main is
com.juergisApps.pdfConverter.Test) that reproduces the problem.
