Replacing the -

A while back I got this fix for escaping quotes


<xsl:template name="cleanQuote">
<xsl:param name="string" />
<xsl:if test="contains($string, '&#x22;')"><xsl:value-of
    select="substring-before($string, '&#x22;')" />\"<xsl:call-template
    name="cleanQuote">
                <xsl:with-param name="string"><xsl:value-of
select="substring-after($string, '&#x22;')" />
                </xsl:with-param>
        </xsl:call-template>
</xsl:if>
<xsl:if test="not(contains($string, '&#x22;'))"><xsl:value-of
select="$string" />
</xsl:if>
</xsl:template>

What do I need to change to make it escape the - ?
I assume &#x22; is the code for "
so what is the code for - 

Thanks!
