GetGlyphIndices() or Uniscribe's ScriptGetCMap() would be OK for checking
coverage for small Unicode blocks such as Gothic (27 codepoints) or even
Mathematical Alphanumeric Symbols (992 codepoints), but I suspect your
application would freeze if you tried to use it to work out exact codepoint
coverage of CJK-B (42,711 codepoints) and PUA-A and PUA-B (65,534 codepoints
each).
