Jinja, a Python template engine, does something like that. When you include a string in a template, it's automatically escaped, but you can disable that by wrapping the string in a Markup object. You can also use the Markup class directly: >>> foo = u'I <3 you.' >>> bar = Markup(u'<h1>') + foo + Markup(u'</h1>') >>> print bar <h1>I &lt;3 you.</h1>
