Select all that apply.
A. In any system (after release 6.10) by specifying the program has Unicode checks active.
B. By running Transaction UCCHECK.
C. Only in a Unicode system or as part of a conversion to a Unicode system.
D. Cannot be enforced.

Explanation
SAP provides the tools to perform or enforce the Unicode checks prior to your actual conversion. The ability to enforce Unicode checks exists in any release after release 6.10 (when Unicode was supported) without the need to actually convert to Unicode.
The recommendation is to turn the check on as soon as possible to minimize the number of changes to developed programs.
It is better to develop new programs correctly rather than possibly introduce an issue when going back to make a change to the program later.
So the correct answers is A and B.
