Typesetting East Asian languages on the web
summary
Explains how to balance web font design and performance using practical tools and numbers: prefer WOFF2 for compression, use @font-face with Unicode-range to load fallbacks, and expect CJK fonts to cover >30,000 glyphs (minimum ~7,000 glyphs for simplified, ~13,000 for traditional). Shows Firefox devtools font panel and font highlighter, demonstrates variable fonts for size/performance gains, and applies writing-mode and text-orientation for vertical layout. Notes text-combine-upright is supported only partially and that flexbox+vertical had cross‑browser bugs that were fixed after reporting.
