I found out the Using Dynamic DNS for your dynamic IP micro-howto didn't render correctly as it was using ISO-8859-1 as character set while the webserver for idefix.net has been configured to give UTF-8 as default character set. This howto is generated using DocBook so I dug into the bit of config.xsl where this was set and found after some searching that there is a config variable for the html 'chunker' named chunker.output.encoding which was easy to set:

<xsl:param name="chunker.output.encoding">UTF-8</xsl:param>

For 'html-nochunks' it was a bit harder until I found Output encoding in docbook which has the right bit of code:

<xsl:output method="html"
            encoding="UTF-8"/>

And now the Using Dynamic DNS for your dynamic IP micro-howto and Draadloos netwerk uitleg en installatie look correct again.

There may be other (older) html documents on this server with other character set breakage.
