    I haven't checked, and I would not bother checking in a case like this:

    If it is reserved space, it does not matter whether something is planned
    there now. It's incorrect to use such code positions anyway, even if you
    would thereby anticipate their future assignment. Private use code
    positions are a better choice.

    In _fonts_, the situation may be different: a position in a font need
    not correspond to a Unicode code position. This depends on the encoding
    of the font. The crucial question is: if you take some Unicode encoded
    data and use the font to render the text, will unassigned code numbers
    be presented properly (using symbols for unassigned positions) or as
    some graphic characters?
