mathematical symbols in fo with fop

[Roel Vanhout <ro...@riks.nl>]

Hello all,

I'm trying to display mathematical symbols (more specifically the square 
root symbol) in a pdf document, and a very basic version of the source 
fo document looks like this:

<?xml version="1.0" encoding="iso-8859-1"?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
   <fo:layout-master-set>
     <fo:simple-page-master master-name="my-page">
       <fo:region-body margin="1in"/>
     </fo:simple-page-master>
   </fo:layout-master-set>
   <fo:page-sequence master-reference="my-page">
     <fo:flow flow-name="xsl-region-body">
       <fo:block>Hello, world! --&#8730;--</fo:block>
     </fo:flow>
   </fo:page-sequence>
</fo:root>

However, when I process this file with FOP, the pdf has the following 
content:

Hello, world! --#--

I'm using FOP 0.20.4 on Windows XP. I've been looking through the Times 
New Roman font on XP with the Windows character map utility, and I can 
see the square root symbol in there. What am I doing wrong? Is this 
simply not supported? I tried XEP also, and that processor didn't 
display anything at all - this leads me to believe that the mistake is 
on my part somewhere :) Thanks for all hints!

cheers,

roel

This means the current font does not have a glyph for the
&#8730; character. Find a font which has a glyph and make
it known to FOP as described in docs/html-docs/fonts.html,
and you're set.
