--- Comment #3 from Uli Schlachter <psychon@znc.in> ---
Looking at the SVG's source, the glyphs have been "rastered". For example:

<symbol overflow="visible" id="glyph0-238">
<g transform="matrix(1,0,0,1,0,3)">
<rect x="1" y="1" width="1" height="1"/>
<rect x="3" y="1" width="1" height="1"/>
<rect x="1" y="2" width="1" height="1"/>
<rect x="2" y="4" width="1" height="1"/>
</g>
</symbol>

I would guess that the size of the raster is about 7x5 and that's also more or
less the equality of the resulting picture.

No idea *why* this happens, but somewhere along the process, some important
information gets lost. Also, no idea if this is Poppler's fault or cairo's
fault.

Adrian?
