Turns out there is an easy way to do this (despite a quick web-search not revealing an obvious solution): just use method xml.Utility.escape.

xml.Utility.escape does not escape e.g. « « see my answer proposal
If you are looking to escape the @ sign in a scala.html file, for instance, using Scala/Play, do @@.
And give the person who provided this answer here How to print @ symbol in HTML with play framework (scala) an upvote.
I came across this page while looking for the above answer, so I just wanted to duplicate it here since other people may end up here as well.

I propose using the function org.apache.commons.text.StringEscapeUtils.escapeHtml4, added into build.sbt by libraryDependencies += "org.apache.commons" % "commons-text" % "1.9"
( xml.Utility.escape does not escape e.g. « « )

This is helpful; I've noticed
xml.Utility.escape does not support anything beyond the default XML entities.Using scala-xml you can create a scala.xml.Text node and print content using toString:
println(scala.xml.Text("<Jack & Jill>").toString)
This will show:
<Jack & Jill>
