Hello, everyone. Apologies in advance if this has been answered
elsewhere, but I have not been able to find a solution to my issue.
I am trying to render PDF content that contains embedded MathML, a
sample of which is contained in the message below. I found the
JEuclid plugin, and have successfully integrated it with Apache FOP
such that my MathML contained in instream-foreign-object blocks gets
passed to the plugin -- the MathML is being rendered by JEuclid,
albeit improperly. The issue I have seems to be with fonts; many of
the valid escape sequences (e.g. −) get rendered as #
characters, as if the FOP renderer encountered a character that was
not in the font family it was using. If I pass the exact same
sample.fo file to the JEuclid MathViewer application at the following
link (requires JDK 1.5 Web Start to run):
http://jeuclid.sourceforge.net/jeuclid-webstart/mathviewer.jnlp
.. the math renders perfectly. I have tried registering the JEuclid
recommended fonts (e.g. DejaVu) with the FOP renderer, and while the
fonts for the body text do change, the equation remains unchanged. I
am not sure if this is an issue with the configuration for FOP or
JEuclid -- the latter is pretty sparse -- so I am hoping someone has
encountered this issue and might be able to give me some pointers.
