    Indeed. There is at least one *national* Standard, GB/T20524-2006
    ("Tibetan Coded Character Set Extension A") which uses the PUA
    [F300-F8FF]. Part B of this standard uses F0000-F16FF.

    These national standards are essentially extensive sets of precomposed
    Tibetan ligatures previously rejected by UTC and WG2 for encoding that
    China then decided to encode in the PUA.
