should we use hostname.toCanonicalHost() instead?

It's worse actually, causes us to fail on the tel example also.

Maybe there is a fix where fix toCanonicalHost logic and then we use it, but maybe that's a good second pass PR once the test is in.

What about just removing the toLowerCase(Locale.US) call completely? I’m trying to avoid having a bunch of code in here that doesn’t get exercised in practice.

It's still public API
@Test
public void thatCatchesErrorsWithBadSession() {
HostnameVerifier localVerifier = new OkHttpClient().hostnameVerifier();
// Since this is public API, okhttp3.internal.tls.OkHostnameVerifier.verify is also
assertThat(verifier).isInstanceOf(OkHostnameVerifier.class);
SSLSession session = TlsUtil.localhost().sslContext().createSSLEngine().getSession();
assertThat(localVerifier.verify("\uD83D\uDCA9.com", session)).isFalse();
}

In Okio this function is called ByteString.toAsciiLowercase() (though to use that one we’d need to roundtrip through a ByteString)

Nice simplification Picasso :) I'll land based on your commit. |

We currently embed externally generated certificates in our unit tests, but we can now generate our own certificates so we should.
