The `div' operator *is* exotic in CFFs since the Type2 format has a
16.16 fixed float type which *must* be used (AFAIK) if you have a
non-integer width.  From the specifcation:

  1) Width: If the charstring has a width other than that of
  `defaultWidthX' (see Technical Note #5176, “The Compact Font Format
  Specification”), it must be specified as the first number in the
  charstring, and encoded as the difference from `nominalWidthX'.

`As the first number' can not be replaced with a solution using `X Y
div'.

Well, I'm rather sure that you won't see `div' in the created OTF...
