I created simple file with Foxit PhantomPDF. The "Title" in document info dictionary contain text with tab, which is written as sequence `\t`. Every creator do that differently. :)

> Regarding to case PDFBOX-3107. There was change in CosWritter.java that if string contains characters CR (0x0d) and LF (0x0a) the string is written in hex format. This may be ok, but PDF specification (7.3.4.2 Literal Strings) explicitly defines more characters that should handle specially.
> I'm providing another version of the code that handles all special characters without transforming to hex format.
