Special letter in file name in search results

Question

I have follow this quid
http://charliedigital.com/2011/12/16/force-file-name-in-sharepoint-2010-search-results/ to change XSL to display file name in search results instead of title. It works very well. I'm happy. But I find a small thing. the special character in file name (e.g.
Ö, Ü ...) cannot be displayed correctly. But before changing those special letter can be displayed in title correctly. How can I do to solve this problem? I put following XSL:
<xsl:otherwise>
    <a id="{concat($currentId,'_Title')}">
        <xsl:attribute
name="href">
<xsl:value-of  select="$url"/>
        </xsl:attribute>
        <xsl:attribute
name="title">
<xsl:value-of select="title"/>
        </xsl:attribute>
        <xsl:if
test="$isdocument">
<xsl:value-of select="filename"/>
        </xsl:if>
        <xsl:if
test="not($isdocument)">
<xsl:choose>
<xsl:when test="hithighlightedproperties/HHTitle[. != '']">
<xsl:call-template name="HitHighlighting">
<xsl:with-param name="hh"
select="hithighlightedproperties/HHTitle"
/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="title"/>
</xsl:otherwise>
</xsl:choose>
        </xsl:if>
    </a>
</xsl:otherwise>

Hi
I think
that special characters are not related to
the change in the XML file
on your personalized results page.
With the original XML
special characters display correctly?
You can use
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<xmp><xsl:copy-of select="*"/></xmp>
</xsl:template>
</xsl:stylesheet>
to see results with another encoding
