When migrating to CUBRID, we must consider column size because of many difference between CUBRID and other databases.
But, most of users didn't know this.
if you want to migrate from ORACLE to CUBRID8.x, you must consider to change column length to x3 or x2.
But, if the target database is CUBRID9 which database have been created by UTF-8, you don't need to consider this issue.
So, we'd better let him know what is differences between the source and the target database which he have selected.
We need to improve this by showing message or getting a detailed version or character-set information from the user.
