About this lesson: This coding and digital skills lesson explores how computers represent text and symbols using binary, ASCII, and Unicode. Students decode and encode messages, use emoji Unicode charts, and compare how devices handle global characters. They complete interactive tasks like binary name building and emoji text threads to understand data representation.

The lesson also covers the history of character encoding and the move from ASCII to Unicode. It shows why Unicode matters in global digital communication today. Designed for classroom or independent learning, the lesson builds logical thinking and computer science skills. It also supports digital skills and awareness.
