This is not a bug; you'll need to use assertIdentical, which uses typesafe
comparison.

With assertEqual, it uses the type unsafe comparison ==. assertIdentical
uses the === comparison operator. With the type unsafe comparison, PHP sees
you're comparing a string to a number and then it coerces the string to a
number. intval("utf-8") results in 0, so the test succeeds because 0 is
equal to 0.
