Well, it may be that the XML output portion of Scala is escaping your
ampersands a second time. For instance, check out this session in the
interpreter:
scala> val title = "Catsby & Twisp"
title: java.lang.String = Catsby & Twisp
scala> val escaped = <span>{title}</span>
escaped: scala.xml.Elem = <span>Catsby &amp; Twisp</span>
scala> val unescaped = <span>{ scala.xml.Unparsed(title) }</span>
unescaped: scala.xml.Elem = <span>Catsby & Twisp</span>
Note that if you embed a String within XML elements, Scala will
automatically escape any ampersands unless you wrap the String in a
scala.xml.Unparsed instance. The second test there will render in the
browser like "Catsby & Twisp", because the ampersand was escaped. I know
you're asking about the Utility object, but I think that would be fixing the
symptom rather than the cause.
