When I compile the following document I see in the output localized
variants for the various glyphs. But copy & paste works only for the
last line. The first two gives notdef chars.
In the pdf e.g. the first glyph has the numbers 2D0E, 2D0F, 2D0D in
the three lines but only for the last there is a unicode mapping:
<2D0D> <5203>.
What can one do to get a mapping also for the other glyphs?
The font can be downloaded here

One can see how the glyphs are replaced under locl:
fonts           > otf direct > feature 'locl', type 'gsub_single',
lookup 's_s_42': replacing U+5203 by single U+F0608
but I can find nothing about tounicode/cmap or something like that.
ok, then you can see the font as seen by context
mtxrun --script fonts --convert SourceHanSans-Regular.otf
(keep track also of its output )
