---------------------------------------
Thanks to you.
Could you point me on your rendering regression tests?
I might need it in the near future.
> Issue in FontMapperImpl#isCharSetMatch when font codePageRange is -1

> 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?
