Embedding font in the PDF, footnote numbering is not superscripted

[Xuan Ngo <xuanngolist@yahoo.ca>]

After embedding Arial Unicode MS font  in the PDF, 
footnote numbering is not superscripted but shrinked.
The number looks like it has a smaller font size.
Can someone help!

For example:
In Docbook:
============
<ulink url="http://www.google.com";>Hello</ulink>

Output in PDF:
============
Hello1<= One here is not superscripted but shrinked

Custom layer:
===========
<xsl:param name="body.font.family">ArialUnicodeMS</xsl:param>
<xsl:param name="ulink.footnotes" select="1"/>

Tools used:
=========
xsltproc.exe
FOP 0.91Beta

	
Thanx!
