ASCII to UTF-8 Conversion

Introduction: As the world becomes increasingly interconnected, the need to understand and work with different character encodings has become essential. ASCII (American Standard Code for Information Interchange) and UTF-8 (Unicode Transformation Format 8-bit) are two commonly used character encodings. In this guide, we’ll explore how to convert ASCII to UTF-8 and provide insights into the conversion process through an ASCII to UTF-8 table.

Understanding ASCII and UTF-8: ASCII is a character encoding standard that assigns numerical values to characters, including letters, digits, punctuation marks, and control characters. Originally developed for the English language, ASCII uses 7 bits to represent 128 characters, with values ranging from 0 to 127.

On the other hand, UTF-8 is a variable-width character encoding capable of representing all Unicode characters. It uses between 1 and 4 bytes to represent characters, with ASCII characters represented using a single byte (equivalent to their ASCII values) and other characters represented using multiple bytes.

ASCII to UTF-8 Conversion Table: Converting ASCII characters to UTF-8 involves representing ASCII characters using their corresponding UTF-8 byte sequences. Below is an ASCII to UTF-8 conversion table showcasing ASCII characters and their equivalent UTF-8 byte sequences:
