    Description

      I tried the "ExtractTextByArea" with a PDF from my bank and go the following stacktrace:

      Exception in thread "main" java.lang.ClassCastException: org.apache.pdfbox.cos.COSName cannot be cast to org.apache.pdfbox.cos.COSDictionary
	at org.apache.pdfbox.pdmodel.font.PDType3Font.readEncoding(PDType3Font.java:70)

	at org.apache.pdfbox.text.PDFTextStripperByArea.extractRegions(PDFTextStripperByArea.java:130)

      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

      dict.getDictionaryObject(COSName.ENCODING)

      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.
