-------------------------------------

Showing font encodings and characters would be great too.

> (This is an idea for [GSOC2015|https://www.google-melange.com/]. But if you want to submit some improvements to the code outside of GSOC2015 now, this is fine. We can always come up with other project ideas for GSOC2015)
> Our command line utility PDFDebugger (part of the command line pdfbox-app get it [here|https://pdfbox.apache.org/downloads.html], read description [here|https://pdfbox.apache.org/commandline/]) needs some improvements:
>    - hex view
>    - view of non printable characters
>    - saving streams
>    - binary copy & paste
>    - show images that are streams
>    - show PDIndexed gradient
>    - show PDSeparation color
>    - show PDDeviceN colors
>    - edit fields
>    - edit streams, while keeping or changing the compression filter
>    - save altered PDF 
>    - color mark of PDF operators
> To see a product with a similar purpose that is better than PDFDebugger, watch [this video|https://www.youtube.com/watch?v=g-QcU9B4qMc].
> I'm not asking to implement a clone of that product (I don't use it, all I know is that video), but we really need something that makes PDF debugging easier. As an example of how the current PDFDebugger prevented me from finding a bug quickly, see PDFBOX-2401 and search for "PDFDebugger".
