Safety notes

  • Glyph-extraction techniques exist against subset WOFF2 files. Consider masking risk when the rendered text is sensitive.

Common mistakes

  • Serving WOFF2 as application/octet-stream instead of font/woff2 can defeat some CDN caching.
  • When self-hosting, use Cache-Control: public, max-age=31536000, immutable for optimal caching.
