The same syntaxes work fine with engine=Innodb.

These are the syntaxes that work with engine=Columnstore-
table level:
CREATE TABLE t1 (id INT, name VARCHAR(40)) CHARSET utf8 ENGINE=Columnstore;
column level
CREATE TABLE t2 (id INT, name VARCHAR(40)CHARACTER SET utf8) ENGINE=Columnstore;
CREATE TABLE t2 (id INT, name VARCHAR(40)CHARACTER SET 'utf8') ENGINE=Columnstore;
CREATE TABLE t2 (id INT, name VARCHAR(40)CHAR SET utf8) ENGINE=Columnstore;
