Hi Bruno and Paulo,
I found that the output intents info written in PdfWriter is slightly wrong.
In line 2508 in class PdfWriter in the setOutputIntents method it says
out.put(PdfName.INFO, new PdfString(registryName, PdfObject.TEXT_UNICODE));
instead of
out.put(PdfName.INFO, new PdfString(info, PdfObject.TEXT_UNICODE));
I am currently using iText version 1.4.5. I also checked the source of itext-paolo-155 and also found it in there.
Best regards,
Leander
