Leonard Wicke updated PDFBOX-5849:
----------------------------------
Description:
*Description*
We are using Apache PDFBox 3.0.2 in our software and have the following issue.
Its likely that other other versions of PDFBox 3 are also affected. We did not
have this issue before with Apache PDFBox 2.
We want to write a String using the font FreeSansBold.
The font is loaded via PDType0Font#load from a TTF-file.
If we load the font with embedSubset=true than the following exception occurs:
{code:java}
java.lang.ArrayIndexOutOfBoundsException: Index 2941 out of bounds for length
2912
at
org.apache.fontbox.ttf.TTFSubsetter.addCompoundReferences(TTFSubsetter.java:500)
at org.apache.fontbox.ttf.TTFSubsetter.getGIDMap(TTFSubsetter.java:147)

at org.apache.pdfbox.pdmodel.PDDocument.save(PDDocument.java:988)
at org.apache.pdfbox.pdmodel.PDDocument.save(PDDocument.java:944){code}
The reason is the question-mark-character "?". The character "!" also causes an
exception.
Letters like a-zA-Z dont.
This character is first correctly identified as Glyph-ID 34 but then in
PDAbstractContentStream#encodeForGsub converted to 2914 by
GsubWorkerForDevanagari.
This glyph does not exist for this font and causes the exception later in the
code when saving the document when subsetting the fonts.
The exception does not occur when writing the text in the PDPageContentStream.
If we load the font with embetSubst=false then no exception occurs but the
character is not visible/skipped in the pdf.
I have only found old and fixed issues with ArrayIndexOutOfBoundsExceptions
(https://issues.apache.org/jira/browse/PDFBOX-4946).
*Code to redproduce*
you need the font FreeSansBold or another font that causes this problem
{code:java}
PDDocument document = new PDDocument();
File boldF = new File("src/test/resources/fonts", "FreeSansBold.ttf");
TrueTypeFont boldT = new TTFParser().parse(new
RandomAccessReadBufferedFile(boldF));
PDFont bold = PDType0Font.load(document, boldT, true);
PDPage page = new PDPage(PDRectangle.A4);
PDPageContentStream contentStream = new PDPageContentStream(document, page,
PDPageContentStream.AppendMode.APPEND, true, true);
contentStream.setFont(bold, 11);
contentStream.beginText();
contentStream.newLineAtOffset(50, 50);
contentStream.showText("?");
contentStream.endText();
contentStream.close();
document.addPage(page);
document.save(new File("Test.pdf"));{code}
