+If you want to make an object unicode that is not yet unicode
+but don't want to lose the taint information, you can use the
+`soft_unicode` function:
+
+>>> from markupsafe import soft_unicode
+>>> soft_unicode(42)
+u'42'
+>>> soft_unicode(Markup('foo'))
+Markup(u'foo')
+
+Objects can customize their HTML markup equivalent by overriding
+the `__html__` function:
+
+>>> class Foo(object):
+...  def __html__(self):
+...   return '<strong>Nice</strong>'
+...
+>>> escape(Foo())
+Markup(u'<strong>Nice</strong>')
+>>> Markup(Foo())
+Markup(u'<strong>Nice</strong>')
