  14 /**
  15 *   This is an API test for ICU spoof detection in plain C.  It doesn't test very many cases, and doesn't
  16 *   try to test the full functionality.  It just calls each function and verifies that it
  17 *   works on a basic level.
  18 *
  19 *   More complete testing of spoof detection functionality is done with the C++ tests.
