An Introduction to Writing Systems and Unicode (r12a.github.io)

The article explains how major writing systems (with examples from Chinese, Japanese, and Korean) map to Unicode code points, noting differences like Traditional vs. Simplified Chinese and kana width conventions. It also introduces key concepts such as radicals, character sets versus coded character sets, and why early multi-byte and code-page approaches were difficult for multilingual text. The piece concludes that Unicode’s unified repertoire and multiple planes allow many scripts and symbols to be represented in a single encoding without switching systems.
