Hi forum,
so far we tackled it by performing an XSL transformation including an encoding directive to change the output encoding e.g. like this:
<xsl:stylesheet version="1.0"
<xsl:output ... method="xml" encoding="iso-8859-1" ... />
…
</xsl:stylesheet>
and a change of the response content-type header after placing our transformed content into the response body.
