Removing wierd characters in xml output
I am trying to remove strange characters in the xml output. Here's the code and output:
There seems to be encoding issues. I tried to add and convert this from ical to xml:
http://flourishhosting.co.uk/test.php
<xml version="1.0" encoding="UTF-8">
<html xsl:version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<body style="font-family:Arial;font-size:12pt;background-color:#EEEEEE">
<xsl:for-each select="VCALENDAR">
<div style="background-color:teal;color:white;padding:4px">
<span style="font-weight:bold"><xsl:value-of select="URL"/> - </span>
<xsl:value-of select="DTSTART"/>
</div>
<div style="margin-left:20px;margin-bottom:1em;font-size:10pt">
<p>
<xsl:value-of select="SUMMARY"/>
<span style="font-style:italic"> (<xsl:value-of select="calories"/> calories per serving)</span>
</p>
</div>
</xsl:for-each>

Your HTML document is incomplete. You are missing the whole tag head
that the content type meta tag should have, which specifies the content and encoding. Now the browser has to guess what the encoding is and guess wrong.
A valid HTML document has a tag head
with a tag title
where you add the meta tag:
<head>
<title>Page name</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
</head>
