[PATCH 2/2] PDFDoc::setDocInfoStringEntry(): treat value consisting of just the unicode marker as an empty string

Description Jakub Alba 2016-08-23 11:28:25 UTC 
A frontend like glib during string conversion from UTF8 to UTF16-BE inserts the unicode marker and when the input string is empty, then the output consists of just the unicode marker which prevents PDFDoc::setDocInfoStringEntry() from detecting that in reality it's an empty string. It may potentially occur in other places, so I think it should be fixed in PDFDoc::setDocInfoStringEnty(), not in the callers, since converting an empty string to just the unicode marker seems like a valid behavior to me and in a sense such a string is really empty.
