What is the maximum length when Unicode is enabled?

• A. Maximum length is 4,999 characters.
• B. Maximum length is 2,000 characters.
• C. Maximum length is 4,000 characters if Unicode is enabled.
• D. There is no maximum length when Unicode is enabled.

Answer: (C)

When Unicode is enabled, each character can take more storage than a simple ASCII character, because Unicode uses multi-byte encoding. To keep the overall storage footprint the same, the system caps how many characters can be stored. That’s why the maximum length is set to 4,000 characters in Unicode mode. This reflects maintaining the fixed byte budget while accommodating the larger size of Unicode characters. So, the best answer recognizes that Unicode increases per-character storage, leading to a capped length of 4,000 characters. The other options violate this fixed storage rule or assume there’s no limit.
