ABAP Keyword Documentation → ABAP − Reference → Obsolete Language Elements → Obsolete Program Attributes →Obsolete Disabling of the Unicode Check
The program attribute Unicode checks active for activating Unicode checks is active when creating a program. This program attribute cannot be canceled.
The option to modify this program attribute is provided only for reasons of compatibility. It is generally only needed to enable Unicode checks in programs where they are not yet enabled.
Activating the Unicode checks is the only way to ensure that the program can be executed in Unicode systems and in non-Unicode systems, and that the same results are returned in both cases.
For more information, see Program Attributes.
