Comment 3 for bug 369861

Don't have time this AM to try the test case, but I'm seeing a similar situation where a SVGZ saved in some unknown version of Inkscape (file metadata does say 0.46), using an imported PDF, contains character 0001s that the parser doesn't like with a fresh install of Inkscape 0.46-5ubuntu4 on a fresh install of Ubuntu 9.10:

file.svg:493: parser error : PCDATA invalid Char value 1
         id="tspan2654">
</tspan></text>
                        ^
file.svg:635: parser error : PCDATA invalid Char value 1
         id="tspan2736">
</tspan></text>
                        ^
file.svg:971: parser error : PCDATA invalid Char value 1
         id="tspan2934">
</tspan></text>
                        ^
This behavior seems to be somewhat unpredictable, since if I recall correctly I have sometimes generated SVGs from the same PDF with the same version of the software that don't suffer from it. Of course, going through and stripping the illegal characters is a [tedious] workaround.

...

For what it's worth, here is a snippet of the SVG from a "malformed" file, where ^A represents the illegal character, suggesting this is just being passed through from the imported document in violation of some schema that's caught when reloading:

<text
       transform="matrix(1,0,0,-1,93.600528,484.98)"
       id="text2652"><tspan
         style="font-size:7.98000002px;font-variant:normal;font-weight:normal;fo
nt-stretch:normal;writing-mode:lr-tb;fill:#000000;fill-opacity:1;fill-rule:nonze
ro;stroke:none;font-family:Wingdings;-inkscape-font-specification:Wingdings-Regu
lar"
         x="0"
         y="0"
         id="tspan2654">^A</tspan></text>

Importing the same source PDF into 0.46-5ubuntu4 and saving SVG generates the following, stripping/ignoring the character, at least today:

      <text
         id="text2652"
         transform="matrix(1,0,0,-1,93.600528,484.98)">
        <tspan
           id="tspan2654"
           y="0"
           x="0"
           style="font-size:7.98000002px;font-variant:normal;font-weight:normal;font-stretch:normal;writing-mode:lr-tb;fill:#000000;fill-opacity:1;fill-rule:nonzero;stroke:none;font-family:Wingdings;-inkscape-font-specification:Wingdings-Regular"></tspan>
      </text>

I'll attach the source PDF in case anyone cares to examine its use/abuse of Wingdings/control characters in the first place.
