Arabic letters not formed properly after adding Zero Width Space (​)

[kthangavel]

Hi All,
I am trying to generate a PDF report using Apache FOP in Arabic Language .
The report generation is working fine but I have used the following snippet
of xslt for wrapping the data within the cell. 

<xsl:template name="intersperse-with-zero-spaces">
                <xsl:param name="str"/>
                <xsl:variable name="spacechars">
    &#x9;&#xA;
    &#x2000;&#x2001;&#x2002;&#x2003;&#x2004;&#x2005;
    &#x2006;&#x2007;&#x2008;&#x2009;&#x200A;&#x200B;
                </xsl:variable>

                <xsl:if test="string-length($str) &gt; 0">
                        <xsl:variable name="c1" select="substring($str, 1, 1)"/>
                        <xsl:variable name="c2" select="substring($str, 2, 1)"/>

                        <xsl:value-of select="$c1"/>
                        <xsl:if test="$c2 != '' and
        not(contains($spacechars, $c1) or
        contains($spacechars, $c2))">
                                <xsl:text>&#x200B;</xsl:text>
                        </xsl:if>

                        <xsl:call-template name="intersperse-with-zero-spaces">
                                <xsl:with-param name="str" 
select="substring($str, 2)"/>
                        </xsl:call-template>
                </xsl:if>
        </xsl:template> 

After calling this template for all the data , the Arabic characters are not
forming properly and looks mis-formed. For examples , Please check the 5th
column from right to left and Arabic character is not proper.  I am
attaching the sample PDF and fo.xml for your reference. Could you please
help me sort this issue out.
