--- Comment #1 from Marc Mutz <marc.mutz at kdab dot com> --- And no, checking __cplusplus in addition is not an option, since many compilers, GCC included (__cplusplus==1, remember?), do not necessarily bump __cplusplus when they implement enough core features to make something like string_view (which can be implemented in C++11 just fine) work.
