[ https://issues.apache.org/jira/browse/PDFBOX-5124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17298398#comment-17298398 ] Gábor Stefanik commented on PDFBOX-5124: Unfortunately we have no control over what kind of messed up junk other PDF authoring tools put out. And as long as such junk continues to circulate, PDFBox will come across it, and users will blame PDFBox for rendering it "wrong", especially when other PDF readers render it correctly. This is not like with HTML, where back in 2004, Firefox devs could rightfully say, "no, it's Internet Explorer that's rendering that page wrong". HTML can be fixed after it's originally made; with PDF, it's a lot more difficult. > Improperly declared OS2WindowsMetricsTable version (v0 table declard as v3) > in embedded font stops parsing with EOFException > > > Key: PDFBOX-5124 > URL: https://issues.apache.org/jira/browse/PDFBOX-5124 > Project: PDFBox > Issue Type: Bug > Components: FontBox >Affects Versions: 2.0.22 >Reporter: Gábor Stefanik >Priority: Major > Attachments: PDFBOX-5124-new.txt, PDFBOX-5124-old.txt, > PDFBOX-5124.pdf-1-new.png, PDFBOX-5124.pdf-1-old.png, > SZAMLA-20190417-20190012706-ININET-BroadBitHungary-11646-HUF.pdf > > > The attached document contains an incorrectly versioned > OS2WindowsMetricsTable.

There are so many issues occurring in the wild, is that really a reason to hail
them?

I did a quick test with this change (the real change will do proper logging and
use EOF)
{code}
if (version >= 1)
{
try
{
codePageRange1 = data.readUnsignedInt();
codePageRange2 = data.readUnsignedInt();
}
catch (IOException ex)
{
version = 1;
ex.printStackTrace();
return;
}
}
{code}
Text extraction has no differences, rendering has a slight glyph difference.
Were you expecting more than this?
