John Hewson commented on PDFBOX-3513:
-------------------------------------
Indeed, Type 3 fonts are required to have an encoding dictionary. But the spec
has nothing to say on what to do when that is not the case. For non-Type 3
fonts the fallback encoding is StandardEncoding, and I suspect that this is
being used, not WinAnsiEncoding. Alternatively the font could be completely
disregarded.
[~emanuelgreisen], try this instead:
{code}
encoding = new DictionaryEncoding(new COSDictionary());
{code}
Does the text extraction produce the same result?
> PDFType3Font can have Encoding which is not a COSDictionary

> I can read the PDF with evince, pdftk, lesspipe to extract text. I cannot
> upload the file as it is a bank statement with content I will not share.
> Debugging the application I found that the return from PDType3Font.java:69
> {code}
> dict.getDictionaryObject(COSName.ENCODING)
> {code}
> Is an object of type: "COSName" with the name property set to
> "WinAnsiEncoding".
> I hope this helps - despite the fact that I cannot share the example PDF.
