In BaseFont replace with this:
public static String createSubsetPrefix() {
String s = "";
for (int k = 0; k < 6; ++k)
s += (char)(Math.random() * 26 + 'A');
return s + "+";
}

No but you have 1 in 308915776 chances of collision.

I'm sure there are tools that take care of it. I'm doing a new
PdfCopy for splitting and concatenating documents and I'll certainly include
a renaming mechanism.
