How config FOP to print Greek characters [outside Latin1]

Hello all,
I am trying to print Greek characters with fop 0.95 but it seems that fop only accesses the first 255 characters (first page) of the font.
Greek characters are located in the  next page.
When  trying to print the Greek chars are replaced by ###.

Any ideas how to correct this? I am using font embedding via userconfig.xml, and I was told not to include the metric files [that I removed with no progress either]

userconfig.xml:

<fop version="1.0">
  <renderers>
    <renderer mime="application/pdf">
      <fonts>
      
      <font  embed-url="file:///Users/sp/Triboni8080/ginkgo/fopFonts/DINRg.ttf">
          <font-triplet name="DINRg" style="normal" weight="normal"/>
        </font> 
 <!-- Removed: metrics-url="file:///Users/sp/Triboni8080/ginkgo/fopFonts/DINRg.xml"  
               kerning="yes" -->

      </fonts>
    <renderer>
   </renderers>
</fop>
