             Summary: Issue in FontMapperImpl#isCharSetMatch when font codePageRange is -1
                 Key: PDFBOX-4667
                 URL: https://issues.apache.org/jira/browse/PDFBOX-4667
             Project: PDFBox
          Issue Type: Bug
          Components: PDModel
    Affects Versions: 2.0.16
            Reporter: Struve Pierre
         Attachments: OcrB Regular.ttf

Hi I met an issue with a font.

It seems to me that code page range has not been set and then in org.apache.pdfbox.pdmodel.font.FontMapperImpl#isCharSetMatch
-1 is used.

It seems to me that -1 means "open bar".

I was trying to find a font that matches CHINESE_SIMPLIFIED (cidSystemInfo.getOrdering{color:#9876aa}(){color}.equals{color:#9876aa}({color}{color:#6a8759}"GB1"{color}{color:#9876aa}){color}),
and due to the -1 this font was matched and unluckily it was the one picked.

Do you think we can make a special case for -1 (return false)?

Is there any font currently that matches all code page ranges?
