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).
