nsAutoString myStr(L"Hello"); bool isEqual = myStr.EqualsASCII("Hello");In the above code, we create an nsAutoString object called myStr that stores the Unicode string "Hello". Then, we use the EqualsASCII function to compare myStr with the ASCII-encoded string "Hello". Since the two strings are identical in value, the isEqual variable will be set to true. The nsAString EqualsASCII function is part of Mozilla's XPCOM framework, specifically the nsStringAPI.h header file.
