Question: How should terminals handle text strings for display that start with a specific marker, according to Unicode support requirements in Transparent end-to-end Packet switched Streaming Service (PSS)?
Option 1: Ignore the marker and assume UTF-8 encoding.
Option 2: Recognize the marker (﻿) as an indicator for UTF-16 encoding but only if it's byte-reversed.
Option 3: Recognize the marker (﻿) as an indicator for UTF-16 encoding, in the specified byte order, and process the string accordingly.
Option 4: Treat the marker as part of the ASCII character set.
Explanation: According to the Unicode support requirements, if a text string for display starts with a UTF-16 BYTE ORDER MARK (﻿), it indicates that the string is in UTF-16. Terminals are required to recognize this byte-order mark in its specified order and process the string as UTF-16, ensuring correct decoding and display of characters.
