Description

Since you're suggesting in your blog article on centering (https://tonsky.me/blog/centering/) that all font designers should make sure to set the metrics so that ascender - cap-height = descender, I was wondering if your own font will switch to this as well.

Currently it seems that it does not fulfill this requirement:

  • Ascender 1800
  • Descender -600
  • Cap Height 1377
