This exercise explores ASCII and Unicode conversion. The following table shows strings of characters. $$ \begin{array}{|l|l|} \hline \text { a. } & \text { hel10 world } \\ \hline \text { b. } & 0123456789 \\ \hline \end{array} $$ $[5]<2.9>$ Translate the strings into 16-bit Unicode (using hex notation and the Basic Latin character set).

This exercise explores ASCII and Unicode conversion.
The following table shows strings of characters.
$$
\begin{array}{|l|l|}
\hline \text { a. } & \text { hel10 world } \\
\hline \text { b. } & 0123456789 \\
\hline
\end{array}
$$ $[5]<2.9>$ Translate the strings into 16-bit Unicode (using hex notation and the Basic Latin character set).

Key Concepts

ASCII

ASCII stands for American Standard Code for Information Interchange. It is a character encoding standard that represents text in computers and electronic devices using numerical codes. Originally designed to encode 128 characters, it forms the basis for many modern text encoding systems, serving as a subset of Unicode.

Unicode

Unicode is a comprehensive character encoding standard designed to support text for virtually all writing systems. It assigns a unique code point to every character, allowing for consistent representation and handling of text across different platforms and programs. Unicode includes ASCII as its first 128 characters, providing backward compatibility while extending support to a much wider range of characters.

Hexadecimal Notation

Hexadecimal notation is a base-16 number system used to represent numerical values in a compact format. In the context of character encoding, hexadecimal is often used to express the numerical code points assigned to characters. This notation is particularly useful when working with Unicode because it provides a clear and concise way to denote 16-bit or larger values.

Character Encoding

Character encoding is the process of converting characters from a written language into a specific sequence of bytes or numbers that a computer can store and process. This includes mapping each character to a numerical code according to a defined standard, such as ASCII or Unicode, thereby enabling consistent representation and manipulation of text.

Basic Latin Block

The Basic Latin block is a subset of Unicode that covers the standard Latin characters used in English and many other Western languages. It includes the 128 characters originally defined by the ASCII encoding scheme. When converting text into 16-bit Unicode, characters from this block are represented by their corresponding Unicode code points, typically noted in hexadecimal form.
