And connecting this to Docbook, the conversion of characters
from Framemaker to Docbook XML needs to map them to the ISO entities
listed in the Docbook iso-*.ent files included with
the Docbook DTD.  For example, in iso-tech.ent you see:

<!ENTITY infin  "&#x221E;"> 

The FrameMaker infinity character
should be converted to "&infin;" in your Docbook XML
files so you have a nice mnemonic entity.
The ent declaration identifies it properly by
its Unicode character in XML, and Norm's stylesheets
should render that Unicode character in whatever output format
you choose, including HTML.
