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