Using the CorelDraw PublishtoPDF feature to automate creation of PDFs and then using PDF clown to add bookmarks and amend document properties. CorelDraw saves the title as a Hex string and not a string literal. The "title" is the same as the underlying CDR filename. When attempting to change the title using PDFClown, an execption is thrown "Input is not of a correct format" or "Odd number of characters". Opening the file in Acrobat and then do a "Save As" converts the Hex string into a string literal and allows it to be changed by PDFClown.
The attached PDF has been created using CorelDraw and has a a title of <feff0054006500730074002e006300640072> or (Test.cdr).
