<Vlad> scribenick: Ned

Garret: spent last couple weeks taking c++ client code for patch subset to WebAssembly for running in a browser
... demo

[Demo compares PFE and Unicode range when changing text on a web page.]

Garret: Note that Unicode range breaks kerning for, say, Vietnamese and Latin.
... Many bytes saved with PFE for Chinese.

Jason: Would this harness also help with testing of privacy concerns?

Garret: Yes, can be used for several purposes.
... [call for suggestions]

Chris: Add samples with shaping languages.

Garret: Would like to add Indic.

Vlad: Network latency.

Chris: Server load.

Garret: Not sure how best to represent load but will consider.

glyf transform

Garret: Next topic.
... Reviewing the effect on performance of adding woff2 glyf transformation to patch subset patch computation for several scripts.
... Results are promising.
... Some questions on how to interpret results for different network speeds.

Backwards compatibility.

https://github.com/w3c/PFE-analysis/blob/master/design/backwards_compatibility.md

Garret: Using a custom header along with GET request can trigger preflight request, meaning an undesirable roundtrip.
... Leaning towards option 1 [GET with parameters in query string]
... How to produce a spec?

Chris: Use bikeshed.

Vlad: Only one possible meeting remaining before EOY.

Garret: Will be out next week!

Vlad: That answers that!

<chris> Maybe instead of @font-face format, use supports? https://drafts.csswg.org/css-fonts-4/#font-face-src-requirement-types
