Using accented characters in XML

I have an XML element:
<link name="editUser">Éditez un client</link>

When I display it using xslt, it appears as:
?itez un client

I'm quite new to xml / xslt but in my limited understanding, I figure one of
several things might be happening:
-I'm missing some declaration or processing instruction in my stylesheet
-my xsl processor has some problem or hasn't been properly configured
-I need to define a dtd for my xml document, wherein I specify some kind of
entity (did that make any sense?)

I don't which direction I should start looking for my answer =)
