Re: Cross-WG Collaboration: Procedural Fonts for PM-KR CG (Building on WOFF Legacy)

Hi Daniel,

Thank you for reaching out. I am Vladimir Levantovsky, co-chair of the WebFonts WG. 

Quick question - how would [in your vision] procedural fonts support multilingual & advanced typography - complex scripts / contextual substitutions / variable fonts / etc.?

Thank you,
Vlad

The collaboration between an electrical engineer from Brazil and mathematician from the Kingdom of the Netherlands is the first truly groundbreaking joint effort between a MERCOSUR country and a European Union country, marking the beginning of advanced collaboration between MERCOSUR and the European Union in key frontier technologies.
