original file

Reading a PDF through poppler and outputting with cairo removes content in
special cases.

To reproduce the error in a minimal form i've taken the pdf2ps.c demo and
replaced the surface creating with cairo_pdf_surface_create(...)

I've narrowed it down to; the error seems to happen when a text block contains
the sequence "1A". If i changed that to "1a" no error occured.

I know my cairo version is old, but I have reports it doesn't work on newest
stable either, but cannot confirm this.

Attached are bug.pdf - the original sample document, and output.pdf, the output
of cairo when simply read/written.
