D875DC53 is according to
http://www.russellcottrell.com/greek/utilities/surrogatepaircalculator.htm
the codepoint 2D453 and this is not a valid unicode point. As a
result copy& paste doesn't work correctly.
A similar example with xelatex writes D835DC53 (remark the 3
instead of the 7) instead in the pdf which gives the correct code
point 1D453 and copies fine.
lualatex gives the faulty value too.
line 228 in font-map should be:
k = k - 0x10000
(not v = ...)
