broken pdf output

Using the following test case:

https://bugzilla.redhat.com/attachment.cgi?id=1008037

the output from

pdftocairo -pdf bug.pdf out.pdf

has what looks like an 'o' with quotes above it in various places instead of a
space.

This bug depends on the substitute font for Helvetica. I reproduced this with
the ghostscript fonts:

pdffonts -subst bug.pdf 
name                                 object ID substitute font                 
    substitute font file
