That hasn't been the case since Acrobat 5 (aka we fixed it in Acrobat 6). Leonard

I don't know where Acrobat stands now but with earlier versions it would get confused with different subset fonts with the same prefix. It may be wiser to call PdfReader.shuffleSubsetNames() just in case.

Hi, while investigating some problems with concatenation of pdf files the question came up if it is neccessary to recreate the "font-subset-prefix" to prevent a name clash. I do not see a obvious problem not doing this in the pdf reference manual. Acrobat does not seem to care. If you run the attached Java class two nearly identical pdf files will be generated "StandardType1Fonts1.pdf" and "StandardType1Fonts2.pdf". In another step these two files are joined in another file "out.pdf". There seems to be no prefix processing. PDFSmartcopy throws out one copy of the font. The last file "out2.pdf" is created by copying "StandardType1Fonts1.pdf" twice into the same file. Because of using the same input file twice the prefix is always the same. There is no big difference - Acrobat shows only one font because of the same name. Are there any known problems using itext's PDFCopy/PDFSmartCopy to merge pdf files?
