Issue
- Can not import double-byte (2-byte) character from third party BACnet device receive error "Property invalid datatype"
- Character support in Building Operation
Product Line
EcoStruxure Building Operation
Environment
StruxureWare Building Operation 1.2 and above
Cause
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.
Here is a reference posted on Microsoft Developers Website: Double Byte Character Sets. The note (second paragraph) of this reference indicates that new applications should use Unicode and that DBCS is a legacy protocol.
Resolution
There are no plans to support double-byte characters. It is recommended that a Unicode standard (UCS-4, UCS-2 or UTF-8) be used.
