Checklist: DBCS application design

When you create an application with double-byte coded character set (DBCS) support, follow these guidelines.

A complete list of these guidelines, as well as a full description of each guideline, is included in Volume 1 Designing Enabled Products, Rules and Guidelines (SE09-8001). For your convenience, a subset of these guidelines is provided in the following table.

Complies Not applicable Rule
Double-byte coded character set code points in the graphic character range must be used only for graphic characters and must not be used for control purposes.
Single-byte meaning must not be drawn from either byte of double-byte coded data.
Double-byte coded character set character generators must be capable of producing user-accessible graphic characters.
The ability to switch between single-byte coded character set and double-byte coded character set and the coexistence of single-byte coded character set and double-byte coded character set in the same session must be possible.
User-interface text modules for double-byte coded character set systems must be loaded separately from the running code.
