StruxureWare Building Operation 1.2 and above


Building Operation supports various language characters as part of Unicode. These characters are usually received in UCS-4, UCS-2 or UTF-8 and sent in either UCS-2 or UCS-4. Double-byte format such as JIS X 0208 character set is not supported.

Below link is a reference posted on Microsoft Developers website. The note (second paragraph) of this reference indicates that new applications should use Unicode and that DBCS is a legacy protocol.


There are no plans to support double-byte characters, and recommend that Unicode standard (UCS-4, UCS-2 or UTF-8) be used.
