The length of a field containing bracketed-DBCS data can range from 4 through 32 767 bytes.
Consider the following when determining the length of a DBCS field:
For example, a field that contains up to 3 DBCS characters, 1 shift-in character, and 1 shift-out character, has 8 bytes of data:
(3 characters x 2 bytes) + (shift-out + shift-in) = 8
