Subject [jira] [Commented] (PDFBOX-4667) Issue in FontMapperImpl#isCharSetMatch when font codePageRange is -1
Date Fri, 11 Oct 2019 08:00:16 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-4667?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16949245#comment-16949245

Struve Pierre commented on PDFBOX-4667:

Thanks for understanding me :)

I have not enough knowledge on pdfbox and fonts to advise on a fix solution.

I just made a test by modifying a font so it would match all code page ranges and it returns
-1 as well. Even if org.apache.fontbox.ttf.OS2WindowsMetricsTable#codePageRange1 is set to
4294967295 converted as int (`ulCodePageRange1 = (int)ttf.getOS2Windows().getCodePageRange1()`)
it is equals to -1.

Can I do something to help.

> 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?
