You need to render them in a font that is able to render those characters. To do that, you need to find a font and then follow the directions on the FOP page re "embedding fonts". A good general purpose font for unicode characters is the cyberbit font from bitstream. You can get it from http://sunsite.compapp.dcu.ie/pub/netscape/communicator/extras/fonts/windows/
You have to pay for it for commercial use.
Here's my userconfig entry for the cyberbit font
<font metrics-file="cyberbit.xml" kerning="no" embed-file="cyberbit.ttf"> <font-triplet name="cyberbit" style="normal" weight="normal"/> </font>
You need to generate the cyberbit.xml file using
java -cp build\fop.jar;lib\xerces-1.2.3.jar;lib\xalan-2.0.0.jar;lib\batik.jar org.apache.fop.fonts.apps.TTFReader cyberbit.ttf cyberbit.xml

For some assigments I need to produce numbered portions of design language. The problem is the special characters like <--(assignment), not equals to, and greater than or equal to symbols.
The unicode numbers are known to me, but when rendered in Fop they show as # symbols and do not appear to render.
Unicodes are: U+2190, U+2264, U+2265, U+2260
