Code pages were once the backbone of character encoding in computers, providing a way to map binary values to text in different languages. However, they had significant limitations, particularly when dealing with multiple languages at once. This article explores the history of code pages, how they were used, and why they have been largely replaced by the modern Unicode standard, which offers a universal character set for all languages.

Explore the essentials of C programming tailored for Arduino users. This comprehensive guide covers variables, data types, control structures, functions, arrays, and pointers, with practical code examples to help you harness the full potential of the Arduino platform.
The world of programming languages is vast and ever-evolving. Over the decades, many languages have been introduced, gained popularity, and sometimes faded into obscurity. Yet, some languages, despite being widely criticized, have managed to maintain a strong foothold in the industry. Conversely, others, once heralded as the future, have declined in use. This article delves into this phenomenon, examining why some languages are resilient despite criticism, while others have fallen out of favor. We will explore these dynamics globally, understanding regional preferences and the historical context that has shaped the programming landscape.
