Deep Dive: Why Character Sets Matter
Computers only understand numbers (binary). To display text, we need an agreed mapping: character set = code number → symbol. Without this:
- Your 'A' might appear as '!' on my computer
- Different countries couldn't communicate digitally
- No emoji 😢
- File sharing would be impossible
Character sets are the Rosetta Stone of computing - the universal agreement that lets all computers speak the same language.
