Exception converting docx, with long pointed list, into pdf

[bs_dellacqua]

Hi all,
I'm usign docx4j 3.3.6;
I have the attached docx file and when I try to convert it into pdf with the following code I've the exception:

public static void main(String[] args) throws Exception {

String regex = null;
PhysicalFonts.setRegex(regex);

String inputfilepath = System.getProperty("user.dir") + "/pdf/InvalidXmlCharacter.docx";
String outputfilepath = System.getProperty("user.dir") + "/pdf/InvalidXmlCharacter.pdf";

WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(new File(inputfilepath));

// Refresh the values of DOCPROPERTY fields
FieldUpdater updater = new FieldUpdater(wordMLPackage);
updater.update(true);

// All methods write to an output stream
OutputStream os = new java.io.FileOutputStream(outputfilepath);

System.out.println("Attempting to use XSL FO");

Mapper fontMapper = new IdentityPlusMapper();
wordMLPackage.setFontMapper(fontMapper);

PhysicalFont font = PhysicalFonts.get("Arial Unicode MS");

FOSettings foSettings = Docx4J.createFOSettings();
foSettings.setFoDumpFile(new File(inputfilepath + ".fo"));
foSettings.setWmlPackage(wordMLPackage);

Docx4J.toFO(foSettings, os, Docx4J.FLAG_EXPORT_PREFER_XSL);

System.out.println("Saved: " + outputfilepath);

}

The reason of the exception seems to be the presence into docx of a long pointed list (A,B,...,Z,AA); if I remove AA the conversion is executed successfully; this problem doesn't occours if I use a numbered pointed list (1,1.1,1.1.1,2,3,...).

Any idea about how to solve the problem ?

Thanks

The FO ends with:

Where does the � come from?!

It looks like the numbering is X, Y, Z, and then the next number should be AA
