…t for harfbuzz (#38704) Replaces a big match statement with a call to `unicode_script`'s `Script::short_name` method which has the same big match statement. We special case `Script::Unknown` because the `short_name` method returns empty string for that variant, but harfbuzz represents it with `Zzzz`. EDIT: `Zzzz` seems to be in the spec so I've sent a PR to `unicode_script` to use it: unicode-rs/unicode-script#23 EDIT: And unicode-rs/unicode-script#24 which would allow us to remove this method entirely.
