Question 9What is the most common Unicode encoding when moving data between systems?1 pointUTF-32UTF-8UTF-64UTF-16UTF-128

Analysis of the Question

To determine the most common Unicode encoding used for moving data between systems, we must consider the various formats presented:

1. UTF-32: Uses 4 bytes for each character. It is not commonly used for data interchange due to its inefficiency in terms of space.

2. UTF-8: This encoding uses 1 to 4 bytes for each character, depending on the character. It is backward-compatible with ASCII and widely adopted for web content and data transfer.

3. UTF-64: This encoding is not standard and does not exist in the Unicode standard.

4. UTF-16: Employs 2 bytes for most common characters but requires 4 bytes for less common characters. It's commonly used in environments like Windows but not as prevalent over all systems as UTF-8.

5. UTF-128: Similar to UTF-64, this is not a recognized encoding in the Unicode standard.

Final Answer

The most common Unicode encoding when moving data between systems is UTF-8.
