Have to admit, I don't know how the font encodes the FONTSIGNATURE, but you can read about this structure at http://msdn2.microsoft.com/en-us/library/ms776424(VS.85).aspx. It does include the Unicode ranges, so maybe it's from the font's OS/2 table. The font folks on the list probably know.

Another thing to check is the Unicode ranges supported field in
the font's OS/2 table. In the font John K. sent, bit 48 was set and
bit 59 was not set. Bit 48 is for CJK symbols and punctuation,
which this font doesn't cover. Bit 59 is for CJK unified
ideographs.
By "FONTSIGNATURE", does Murray mean "DSIG" digital signature?
If so, the DSIG table is supposed to be optional in TTF/OTF.
