Pre Unicode 6.1, two consecutive Fatha’s (or Damma, or Kasra) was the
only way to represent the Quraʾnic successive Tanwin U+08F0-08F2, and it
worked universally (given proper font support) except with Uniscribe.
In short, there can always be legitimate uses of what seems like invalid
input and thus it is not rendering engine’s job to enforce it.
