Research direction
Start with AbstractRememberMeServices#encodeCookie() and AbstractRememberMeServices#decodeCookie() in the 4.0.0.M1 code, then reproduce the round trip using a GBK operating-system default charset. Compare the encoded and decoded values and verify that the two operations are exact inverses under that charset.
