Problem regarding font substitution

[Peder]

Hi all,

I ran across a problem regarding font substitution.
I use font 'x' for my main output. Whenever I come across characters which are 
not included in my font 'x' I want to use the ArialUnicodeMS as catch-all.
So on the fo:root element I specified:  font-family="ArialUnicodeMS"

But now when I come across the following fo:inline

<fo:inline font-weight="bold">Kişar Vari</fo:inline>

The text does not appear bold in the PDF
How come?

In my fop configuration I specified the following entry for the ArialUnicodeMS 
font:
        <font metrics-url="/location to fonts/ARIALUNI.xml" kerning="true" 
          embed-url="/location to fonts/ARIALUNI.TTF">
          <font-triplet name="ArialUnicodeMS" style="normal" weight="normal"/>
          <font-triplet name="ArialUnicodeMS" style="normal" weight="bold"/>
          <font-triplet name="ArialUnicodeMS" style="italic" weight="normal"/>
          <font-triplet name="ArialUnicodeMS" style="italic" weight="bold"/>
        </font>

Do I have to change my configuration?
When I run the transformation I receive the following message:

WARN  Event 
groupId=org.apache.fop.fonts.FontEventProducer,id=org.apache.fop.fonts.FontEventProducer.fontSubstituted,key=fontSubstituted,params={requested=ArialUnicodeMS,normal,700,
 effective=ArialUnicodeMS,normal,400}

How can I prevent this from happening and get the bolded name?

Best regards,

Peder
