Hi,

Working with ISO-8859-1 (input, stymesheet, output), my sample stylesheet
take a text node and set it as an attribute. The string must be URL
escaped, but the conversion is bad, for example :

  "é" is converted as "C3%A9"

I think it is due to the intermediate UTF-8 conversion which convert "é" in
something like "é", and that string is URL encoded. In conclusion, the URL
encoding should be done *after* the UTF8 -> ISO-8859-1 conversion, *not
before*.

(PS: by URL unescaping the attributes values in following output, then
converting to ISO-8859-1 then URL escaping, i got the right result) 

Consider file.xml :

~~~~~~~~~~~~~

<?xml version='1.0' encoding='iso-8859-1'?>
<main><title>Accéder à l'organisation des catégories</title></main>

~~~~~~~~~~~~~

and the following stylesheet (taking the text node and setting as attribute) :
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
            version="1.0">
<xsl:output method="html" encoding="ISO-8859-1"/>

<xsl:template match="main">
<a>
<xsl:attribute name="href"><xsl:value-of select="title"/></xsl:attribute>
<xsl:apply-templates/>
</a>
</xsl:template>

</xsl:stylesheet>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

xsltproc file.xsl file.xml gives :

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<a
href="Acc%C3%A9der%20%C3%A0%20l'organisation%20des%20cat%C3%A9gories">Accéder
à l'organisation des catégories</a>
