Description Florian Haenel 2009-05-07 01:32:35 UTC 
Parantheses are escaped in xmp metadata which leads to conflicts validating the 
pdf as PDFa/1b which requires identical data in pdf properties and xmp
Comment 1 Ken Sharp 2009-10-06 01:23:42 UTC 
This is covered (rather obscurely) in the docuemntation in gs/doc/ps2pdf.htm
under the -sDSCEncoding switch.

If you leave this at the default then no 'encoding' is applied to the data at
all, this includes undoing the escapement of certain characters required by
PostScript to create valid strings.

Setting this switch to PDFDocEncoding as recommended in the documentation does
result in a PDF/A file which works correctly. It does seem unreasonable that we
don't at least undo the escapement of PostScript strings, so I've added code to
do this in revision 10142, patch here:
