            Description

            Converting the attached PDF results in text that looks like the screenshot. This issue actually exists in earlier versions of ICE (4.2). I should have logged it last year.

            This is not a high priority for us but I'm logging it so you are aware of it. I think we can work around it by restructuring the document but I'm not certain.

              Definately some sort of text layout interpretation issue.

              There is a strange (()0.0000 bween the and P. I suspect this 0.000 offset is being handled incorectly. Shouldn't be to difficult to correct the issue.

              Here is another PDF that results in the same problem-- skewed text.

              Very rare corner case where the content stream has a empty strings defined within a TJ string draw operation. When the the empty string was encountered we where jumping to a zero advance instead of the previous advance.
