Embedding font triplets w/ a single TTF file

[Jeff Vannest]

                I am embedding fonts into a PDF document. If I use Arial I can 
use the arial.ttf and arialbd.ttf files for the font triplets 
Arial/normal/normal and Arial/normal/bold respectively.

However, certain fonts only have a single TTF. For example, Arial Unicode MS 
has a single file, arialuni.ttf. When I specify:

        <font metrics-url="arialuni.xml" embed-url="arialuni.ttf">
           <font-triplet name="Arial Unicode MS" style="normal" 
weight="normal"/>
           <font-triplet name="Arial Unicode MS" style="normal" weight="bold"/>
        </font>

...it properly embeds Arial Unicode MS, but I loose all font bolding in my 
document.

Is there another way to do this without loosing font bolding in Arial Unicode 
MS?

(I'm using FOP 0.93 embedded into a java app using version 1.4.2_03 on Windows. 
I used TTFReader to create my metrics.)

Thanks!
