Go Programming: Character Encoding Basics

Have you ever encountered unexpected string lengths or strange characters when working with text in Go, especially with non-English characters? Understanding how Go handles character encodings is crucial for writing reliable and global-ready applications. This course will demystify character encoding in Go, equipping you with the foundational knowledge to correctly process, manipulate, and debug text, ensuring your programs behave predictably with any character set. You will learn the core concepts of character sets, encodings, ASCII, and Unicode, and understand how Go represents strings internally using UTF-8 and the distinction between bytes and runes. You will apply Go's built-in functions and the `unicode/utf8` package for accurate string and rune length calculations, and identify and resolve common issues related to displaying and manipulating non-ASCII characters. Finally, you will practice writing Go code that reliably handles diverse international text without encoding errors. The course begins with the fundamental principles of character encoding, progresses through Go's specific approach to strings and runes, and concludes with practical techniques for managing and troubleshooting text data. This course is designed for beginner Go programmers who want to build a solid understanding of how text is handled in Go. No prior knowledge of character encodings is required.
