Let's compile the following code with {xe|lua}atex:
documentclass{standalone}% or article, doesn't matter
usepackage{unicode-math}
setmathfont{TeX Gyre Termes Math}%% or TeX Gyre Pagella Math, doesn't matter
begin{document}
(ℕ)
end{document}
Upon viewing the result of compilation
(as PDF) in evince, we select the single letter, copy it and paste it into some UTF8-capable text editor such as gedit or emacs. What we get is N, not ℕ. But http://www.gust.org.pl/projects/e-foundry/tg-math/gust_e-foundry-math_fonts-presentation.pdf does mention ℕ as a letterlike symbol, so, I'd expect to get ℕ! Why does it happen? How to get ℕ in the PDF text layer?
EDIT: Reported to evince as https://gitlab.gnome.org/GNOME/evince/issues/1085 . Also cf. https://gitlab.freedesktop.org/poppler/poppler/issues/724 . Let's keep the question open until we are 100% sure that the PDF file produced complies with a PDF specification.

@user0 Yes, it's a viewer issue. I just verified it using Evince, Okular, and Foxit. Evince and Okular only copyN, whereas Foxit correctly copiesℕ.
