BTW, the pages on don't actually reflect reality (i.e. what you get if you call the Windows APIs).

For example, has 0x98 as undefined. In reality, it maps to 0098, as you see on

Similarly, says that 0xFF is unassigned. In reality, it maps to F8F3, as on

[These tables were generated by programmatically calling the Windows APIs on an NT, version 4.0, service pack 5.]

This is not to single out Microsoft -- most vendors' documented mapping tables deviate at least slightly from what their APIs actually do. One of the goals of the character mapping project is to determine precisely what the character mappings are so that we can guarantee accurate transcoding between Unicode and legacy sets. This is crucial in a connected world -- if I generate an XML document or HTML page on one machine, I need to be *very* sure that the mapping is precisely what the receiving machine will interpret.
