              The PDF in question is using an interesting ecodeing format for the font where the differences array is referenced as an indirect object which technically against the specification. Our font parsing assumes that the differences list is of type LIst and thus skips and never parses the data found via the reference.

              Updated the Font class initialization object to take into the account that the differences list could be References object and thus we fetch and parse the respective list notation.

              The PDF now renders correctly.
