DB2 V10.5 BLU只支持UNICODE字符集么？

大家好，今天我在IBM官网下了DB2 V10.5 ESE版本。具体版本为10.5.0.7，没有license，只能试用90。

我创建了一个字符集为GBK的数据库：

db2 "create db testdb automatic storage yes on /mnt/disk1,/mnt/disk2 using codeset GBK territory CN'

数据库创建成功后，我创建按列组织的表：

db2 "create table aaa (col1 varchar(100))IN TBS_DATA1 INDEX IN TBS_IDX1 ORGANIZE BY COLUMN"

结果报错：

DB21034E  The command was processed as an SQL statement because it was not a
valid Command Line Processor command.  During SQL processing it returned:
SQL1233N  The statement failed because the statement includes the use of
functionality that is supported only in Unicode databases or Unicode databases
with specific database collations, but the current database is not a Unicode
database or is a Unicode database with unsupported database collations.  
SQLSTATE=560AA

我的问题是：目前DB2的BLU只支持UNICODE字符集么？无法支持GBK么？我用的是企业版，没有license，难道有license可以支持GBK？还是企业版不支持，高级企业版可以支持GBK？

谢谢大家的支持！
