Tilman Hausherr commented on PDFBOX-4667:
-----------------------------------------
I haven't understand whether this is a bug or a question. I do remember one
problem where a barcode font was chosen, so we excluded that one.
Isn't "-1" = 0xFFFFFFFFFFFFFFFF so all fonts would match?
Re font, try Arial Unicode, that one supports a lot.
I opened the font with DTL OTMaster 3.7, here's the segment from the OS2 table,
all 0. (I didn't try any PDFBox code yet)

> 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?
