StringPrep from utils use java.text.Normalizer to NFKC normalization. But this normalization is not in accordance with RFC 3454 - see mapping table:
http://tools.ietf.org/html/rfc3454#appendix-B.2
Relevant profile description:
http://tools.ietf.org/html/rfc3454#section-3.2
Full test is part of pull request 13, but for basic testing can be used this simple test:
@Test
public void testNormalizationWithNFKC(){
ByteStringBuilder b = new ByteStringBuilder();
String before = "\u0041\u0042\u0043\u0044\u0045\u0046\u0047";
String after = "\u0061\u0062\u0063\u0064\u0065\u0066\u0067";
StringPrep.encode(before, b, StringPrep.NORMALIZE_KC);
assertEquals(after, new String(b.toArray()));
}
