QA / TYPOGRAPHY
PostScript Curves & Advanced Features

Test Case Description Size Action
CFF Outlines (PostScript) Cubic Bézier. Uses math distinct from TTF. Some PDF generators or canvas libraries fail to render CFF tables correctly. 250 KB Download
Advanced Typography Contains Small Caps (smcp), Old Style Figures (onum), and Contextual Alternates. Tests font-feature-settings CSS support. 400 KB Download
Asian CJK (20k Glyphs) Massive font containing Chinese, Japanese, and Korean characters. Stresses memory usage during loading. 15 MB Download

Technical Specs: OpenType (OTF)

  • Cubic Bézier: Unlike TTF (which uses 2 points for curves), OTF uses PostScript Cubic curves (4 points). This allows for smoother, more complex shapes, preferred for high-resolution printing.
  • Format Wrapper: An OpenType file is a wrapper. It can technically contain TTF data (.ttf style outlines) OR CFF data (.otf style outlines).
  • MIME Type: font/otf or application/x-font-otf.

Frequently Asked Questions

Why don’t the “Small Caps” appear on my website?
Simply loading the OTF file is not enough. You must explicitly enable the feature in your CSS using: font-variant-caps: small-caps; or font-feature-settings: "smcp";.
Can I convert OTF to TTF?
Yes, but it is “lossy”. Converting Cubic curves (OTF) to Quadratic curves (TTF) requires mathematical approximation. It usually results in slightly more control points and a minor loss of precision at very large sizes.

How to inspect OTF features?

OTF files are databases of glyphs. Use these tools to see what’s inside.

  • FontForge: The most powerful open-source editor. You can edit the CFF curves directly and modify the kerning tables.
  • Otmaster (Commercial) or FontTableViewer: To inspect the binary tables (GSUB, GPOS) that control ligatures and positioning.
  • Wakamai Fondue: Drop your OTF here to see a list of all CSS features available (like `swsh`, `ornm`) ready to copy-paste.

Developer’s Corner: List Features

Use Python’s fontTools to check if an OTF contains specific OpenType features like Ligatures.

# Python: List OTF Features
from fontTools.ttLib import TTFontfont = TTFont(‘Garamond.otf’)
if ‘GSUB’ in font:
gsub = font[‘GSUB’].table
features = [f.FeatureTag for f in gsub.FeatureList.FeatureRecord]
print(f“Features found: {features}”)
# Output: [‘liga’, ‘smcp’, ‘onum’…]
