I dit copy & paste from okular to kate and I get Foo. in all cases. In
order to visualize the PDF internals I did

qpdf test.pdf --qdf test.qdf (and similarly for test.pdf.pdf) and
opened the qdf file in kate. The mapping is

from lualatex:
%% Original object ID: 11 0
13 0 obj
<<
  /Length 14 0 R
>>
stream
%!PS-Adobe-3.0 Resource-CMap
%%DocumentNeededResources: ProcSet (CIDInit)
%%IncludeResource: ProcSet (CIDInit)

CMapName currentdict /CMap defineresource pop
end
end
%%EndResource
%%EOF
endstream
endobj

from gs:

It really needs four characters: F o . 1 (page number)
