Feature Request

Is your feature request related to a problem? Please describe:

TiDB doesn't support gdk encoding when creating a table.

e.g.

CREATE TABLE Untitled  (
  `ID` varchar(50) CHARACTER SET gbk COLLATE gbk_chinese_ci NOT NULL,
  `APP_ID` varchar(50) CHARACTER SET gbk COLLATE gbk_chinese_ci NULL DEFAULT NULL,
  PRIMARY KEY (`ID`) USING BTREE
) ENGINE = MyISAM CHARACTER SET = gbk COLLATE = gbk_chinese_ci ROW_FORMAT = Dynamic;

Thanks for your attention, @elitecodegroovy !
gbk supports will be on our long-term plan.
