There are two problems:  it doesn't call setlocale().  The other is that
the ch variable in selectCommunication() should be an int rather than a
char.  That's causing it to be passed to form_driver() as -19 rather than
237 (sign-extension).  g++ warns about this because the case statement
cannot be properly matched either:

compiling demo (obj_s)
../c++/demo.cc: In function `void selectCommunication()':
../c++/demo.cc:92: warning: overflow in implicit constant conversion
../c++/demo.cc:100: warning: overflow in implicit constant conversion
../c++/demo.cc:109: warning: overflow in implicit constant conversion
