How can I use HTML character entities inside EL in JSF?

I want to use the em dash in a value attribute for an h:link component.

Here is my attempt (currently not working):

<h:link value="#{somethingHere} &mdash; #{anotherHere}">
    <f:param name="identifier" value="#{somethingHere.identifier}" />
</h:link>

This results in a FaceletsException:

FaceletException: Error Parsing /index.xhtml: Error Traced[line: 13]
                The entity "mdash" was referenced, but not declared.
at com.sun.faces.facelets.compiler.SAXCompiler.doCompile(SAXCompiler.java:394)
...

I know I can use an HTML anchor instead, but is there a way to do it inside an Expression Language (EL) expression? What is the correct way to do this?
