Hello and thanks for the invite. I have been doing font engineering for Cantonese (www.visual-fonts.com) and I am curious about the technical side.

1. How did y’all prepared that huuuuuge 10,000 jyutcitzi set? Some kind of opentype.js extraction of components, squish them as SVG, then re-save?

2. Am I correct that it’s a 1-to-several mapping from jyutping to jyutcitzi? (the several being that of choosing “semantic side”)

3. Why are all the tonal marks in the same place (up-right)? JCZ is pretty crowded as it is, and on smaller screens the distinction of the tonal marks (esp ` “) can be hard to read. I think positioning on lower right for 4-5-6 (jyutping), continues the 陰陽 tradition while making it easier to read at a glance.

4. (not font related) Do you have online tooling to convert jyutping->JCZ, or character->JCZ?
