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?
