Old Zed Fonts

Previously, Zed shipped with Zed Mono and Zed Sans, customized versions of the Iosevka typeface. You can find more about them in the zed-fonts repository.

Here's how you can use the old Zed fonts instead of Zed Plex Mono and Zed Plex Sans:

1. Download zed-app-fonts-1.2.0.zip from the zed-fonts releases page.
2. Open macOS Font Book.app
3. Unzip the file and drag the ttf files into the Font Book app.
4. Update your settings ui_font_family and buffer_font_family to use Zed Mono or Zed Sans in your settings.json file.

{
  "ui_font_family": "Zed Sans Extended",
  "buffer_font_family": "Zed Mono Extend",
  "terminal": {
    "font-family": "Zed Mono Extended"
  }
}

5. Note there will be red squiggles under the font name. (this is a bug, but harmless.)
