would have been impossible otherwise. Text was used mainly to add legends and
headings to numeric output, often using a very limited character repertoire, maybe even
lacking lowercase letters. As the cost of computing has dropped, computers have be-

computers as communicators rather than calculators. People want to communicate in
different languages, and we also use notation systems that may require rich repertoires
of characters.
Unicode was developed to help make this both possible and smooth. Unicode was first
