[NTG-context] read PDF metadata from other file

Dear list, I have the following sample: \starttext \setupinteraction [state=start, title={\cldcontext{pdfe.open("b.pdf").Info.Title}}] \null \stoptext From a document composed with \insertpages, I need to transfer medatada. But I get the raw value "feff0061" (which I guess it may be introduced by lpdf.pdfunicode). How can I get the pure text value, so I can transfer metadata from one PDF document into another PDF document? Many thanks for your help, Pablo -- http://www.ousia.tk
