test case

C++11 added the header file <cuchar> (a wrapper around the C header file <uchar.h>). See https://en.cppreference.com/w/cpp/header

$ cat foo.cc
#if __cplusplus >= 201103
#include <cuchar>
#endif

$ c++ -c foo.cc
foo.cc:2:10: fatal error: 'cuchar' file not found
#include <cuchar>

FYI, it seems there's a similar one.

The assignee is clearly aware of the fact that cuchar is missing.
