-/** |
- * Tests cases for {@link ByteString#isValidUtf8()}. This includes three |
- * brute force tests that actually test every permutation of one byte, two byte, |
- * and three byte sequences to ensure that the method produces the right result |
- * for every possible byte encoding where "right" means it's consistent with |
- * java's UTF-8 string encoding/decoding such that the method returns true for |
- * any sequence that will round trip when converted to a String and then back to |
- * bytes and will return false for any sequence that will not round trip. |
- * See also {@link IsValidUtf8FourByteTest}. It also includes some |
- * other more targeted tests. |
