The Acrobat Reader Help mentiones it yet I have not understood the exact
format as the prefs are different then shown in the help (
$HOME/.acrobat/prefs).

I have tried using thd db2xpdf.xsl that comes with XEP and the bookmarks
as seen below do have the correct characters. yet the code in fop.xsl is
also used by xep.xsl and a character conversion is done. So since there
is a translation done Even if there is correct fonts for the bookmarks.
It is not possible to see them as they do not exsit anymore. Maybe this
feature should be removed or added as a parameter to the stylesheets 
Acrobat_compatibiliy_ mode

The db2xpdf.xsl generates this

<rx:bookmark-label>1.2.2. SpamAssassin ayar dosyas&#305;n&#305;n
d&#252;zenlenmesi</r x:bookmark-label>

Docbook generates this

<rx:bookmark-label>1.2.2. SpamAssassin ayar dosyasinin
düzenlenmesi</rx:bookmark-label>


xep.xsl has the a-dia, a-asc translation coming from fop.xsl
.....
<xsl:if test="$bookmark-label != ''">
<rx:bookmark internal-destination="{$id}">
       <rx:bookmark-label>
            <xsl:value-of select="translate($bookmark-label, $a-dia, $a-asc)"/>
       </rx:bookmark-label>
       </rx:bookmark>
</xsl:if>
