Python Word Count with Unicode and Non-ASCII Characters

Processing text in the modern world requires handling characters from dozens of different languages, symbols, and emojis. Standard string operations often fail when encountering non-ASCII or multi-byte characters, leading to inaccurate calculations or application crashes. This text-based course teaches you how to handle Unicode data confidently in your Python applications. You will learn to parse, normalize, and accurately count words and characters regardless of their origin, moving beyond basic ASCII limitations to write production-ready code. What you will learn: Understand the core differences between ASCII, Unicode, and UTF-8 encoding standards; Practice handling multi-byte characters and emojis without breaking your string manipulation logic; Apply Python's built-in unicodedata module to normalize text and strip accents; Implement robust regex patterns that support non-English scripts and special characters; Build a complete, error-tolerant word counting utility that processes multi-lingual inputs; Write unit tests with pytest to verify your text processing logic against diverse encodings. We begin with the foundational concepts of character encodings and Python's internal string representation, then move step-by-step through practical text-processing scenarios and modern coding practices. This course is designed for beginner-to-intermediate Python developers who want to write reliable, globally compatible text-processing scripts. No advanced encoding experience is required.
