PDF 1.2

Info dictionary

A document's trailer may contain a reference to an Info dictionary that provides
information about the document. This optional dictionary may contain one or more
keys, whose values should be strings. These strings may be displayed in an
Acrobat viewer's Document Info dialog. The characters in these strings are
encoded using the predefined encoding PDFDocEncoding, described in Appendix C.
Note Omit any key in the Info dictionary for which a value is not known, rather
than including it with an empty string as its value.
