Inkscape fails to correctly save imported PDF page as SVG (invalid Char values)

[Frédéric Parrenin]

Steps to reproduce:
- open the attached pdf file, select page 9
- save the page as an inkscape svg file
- close inkscape
- re-open the produced svg file with inkscape
=> the page is corrupted, e.g., the included graph is missing

I forgot to add that I use inkscape 0.48 on debian 8.

Reproduced with Inkscape 0.48.5 r10040, 0.91 r13725, Inkscape 0.91+devel r14285 on OS X 10.7.5:
The saved SVG file fails to render as expected, and produces several console warnings on open (parser errors related to character data in text content).

Console warnings from version saved with Inkscape 0.91+devel r14285, poppler 0.35:

Import via poppler (available in Inkscape >= 0.91) saves and reopens as expected:
Attached SVG file was created and saved with Inkscape 0.91+devel r14285 on OS X 10.7.5 (poppler 0.35, cairo 1.14.2).
