Declare UTF-8 character lenght in SQL TABLE not in bytes

See this idea on ideas.ibm.com

Currently, when I create a new table and declare a field, for example, of type CHAR(10) UTF-8, the system only allows for 10 characters if each character is 1 byte in size. If a character occupies 2 or more bytes, the field length is no longer sufficient. For example, if I need to insert 10 characters where each character takes up to 4 bytes, I would need to declare the field as 40 bytes long. It would be ideal if, when I declare a field with a length of 10, the system allows for 10 characters regardless of the byte size of each character.

    IBM does not intend to provide a solution to this Idea at this time, so it is being closed.

    We cannot change the storage length attribute of a character column defined with CCSID 1208 to be 4 times the defined length. Many applications rely on the existing behavior, and many database designs have included an expansion factor in their length definitions. This change would be possible by adding a new clause on the column definition, but we don't intend to invest in this solution at this time. Instead, the user must do their own multiplication of the maximum number of characters by 4 and use that for their character column length value.

    How would you expect this to work if you declare it CHAR(10), and it allocates 40 bytes and you insert a value of "A23456789012345"   Would that get truncated to 10 characters, even though 40 bytes is more than sufficient?   How would this effect existing tables that expect the old way.  At a minimum we'd need a new keyword or something to distinguish the old way from the new way.
