Thank you for testing.
However, my result is different from yours. mine is:

%!PS-Adobe-3.0 Resource-CMap
....
1 beginbfchar
<1ED0> <FFFD>
endbfchar

In your result, <027B> is glyph index of U+3002 itself.
<1ED0> in my result is glyph index of "vrt2" substitution of U+3002.
It seems that in your case, vrt2 gsub feature has not been in operation.

Best,
