In Java, which of the following can text containing both right-to-left and left-to-right scripts be displayed correctly?

The correct answer is Unicode encoding because it is specifically designed to support a wide variety of characters from different languages and writing systems, including both right-to-left (RTL) scripts like Arabic and Hebrew, and left-to-right (LTR) scripts like English and Spanish. Unicode assigns a unique code point to each character, ensuring consistent representation and manipulation of text across different platforms and languages.

This broad compatibility is essential for rendering multilingual text properly. In contrast, ASCII encoding only supports a limited range of characters (primarily the English alphabet and some control characters) and would not be able to handle the complexity of various scripts. Binary and hexadecimal encoding also do not pertain to character representation in the same way as Unicode; they are instead methods of representing data at a lower level and lack the necessary design for handling multiple scripts effectively. Thus, Unicode is the preferred encoding method for applications that need to support diverse text display requirements.
