program o30_301
  character(2) hi
  !$omp atomic write
    hi = 'hi'
 !$omp end atomic
end program
```

Fails with `not yet implemented: Unsupported atomic type`. The wording of the standard is that atomic operations should operate on "scalar variables of intrinsic type" (OpenMP 5.2 section 4.3.1.3).

In Fortran 2023, a scalar variable is defined (3.119) as "data entity that can be represented by a single value of the type and that is not an array". I think that means that a the `character` variable in the above example is scalar and of intrinsic type.

gfortran and classic flang do not allow character variables in atomic types.
