> 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.
