---------------------------------------

Thanks to you.

Could you point me on your rendering regression tests?

I might need it in the near future.

> 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?
