Sending string literals to FORTRAN~77 subroutines/functions is supported for Lapack/Blas-routines, and the strings are \textsc{nul}-terminated for compatibility with C.
The strings should be UTF-8 encoded similarly as for C to be compatible with C, even though the support in FORTRAN~77 is unclear and it is not relevant for the Lapack/Blas-routines.
Returning strings from FORTRAN~77 subroutines/functions is currently not supported.

Enumeration types used as arguments are mapped to type int when calling an external C function, and to type \lstinline!INTEGER! when calling an external FORTRAN function.
