      "Prior to Unicode version 4.1 (2005), it was assumed that Coptic would be
      entered using the Greek alphabet as encoded in the Greek and Coptic block
      of Unicode (starting at U+0370). Some [7] Coptic characters derived from
      Demotic Egyptian were [therefore] assigned codepoints U+03E2-03EF.
      With Unicode 4.1, a separate block was added containing the whole
      alphabetic sequence* and some dialectical variants: the block is named
      Coptic and starts at U+2C80. Thus it is no longer expected that Greek
      codepoints will be used."
      (*other than the 7 characters in the Greek block)
      Apparently, MS Ofc up to 2003 used a different sort than is now used
      in MS Ofc. What to do? I haven't tested this, but there is a capability
      of creating a custom sort (in Excel at least). Whether it works on
      individual letters within words, or just on whole words, I don't know.
      Nor do I know if there's a similar function in MS Access. What I do
      know is that the way the Coptic letters are located in Unicode defeats
      one of the expected advantages of using a Unicode font - namely
      the expectation that Coptic words would sort properly.
