document( URI ) with accented chars fails

  Hello !

  I have a little problem : URI inside a bdocument()bB9 is
ignored when the filename contains accented (UTF-8)
character(s).

  When applying the XSLT on the source with the sample
2 files below, with the following command

~~~{Command line}
$ xsltproc multifiles.xsl files-list.xml
~~~

I expect the following result :

~~~{expected result}
<?xml version="1.0" encoding="UTF-8"?>
<root>
  <el>element 1</el>
  <el>element 2</el>
  <el>element 3</el>
</root>
~~~

but I only get the `el`s from the ASCII only filename.

~~~{output}
<?xml version="1.0" encoding="UTF-8"?>
<root>
  <el>element 1</el>
</root>
~~~


~~~{multifiles.xsl}
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:output encoding="UTF-8" indent="yes"/>
  <xsl:template match="/">
    <root>
      <xsl:for-each select="document(/fileslist/filepath)/root/el">
        <xsl:copy-of select="." />
      </xsl:for-each>
    </root>
  </xsl:template>
</xsl:stylesheet>
~~~

~~~{files-list.xml}
<?xml version="1.0" encoding="UTF-8"?>
<fileslist>
  <filepath>filename-without-accented-char.xml</filepath>
  <filepath>filename-with-utf-8-accented-char-C).xml</filepath>
</fileslist>
~~~
(When i add files to the `files-list.xml`, the ones
containing accented chars are consistently ignored.)

~~~{filename-without-accented-char.xml}
<?xml version="1.0" encoding="UTF-8"?>
<root>
  <el>element 1</el>
</root>
~~~

~~~{filename-with-utf-8-accented-char-C).xml}
<?xml version="1.0" encoding="UTF-8"?>
<root>
  <el>element 2</el>
  <el>element 3</el>
</root>
~~~

  Do i miss something or is it a libxslt bug ?
  
  Thanks for your time !
