Originally created by @akritikos on GitHub (Nov 29, 2019).

Environment

Windows build number: 10.0.18363.0
Windows Terminal version (if applicable): 0.7.3291.0

Any other software?

Steps to reproduce

  • Add a monospace TrueType font and configure a profile to use it
  • Add a second font and configure it as fallback to the first using font linking
  • Open Windows Terminal
  • Characters are reported as missing despite existing in the fallback font

Expected behavior

Characters rendered using the main font, missing glyphs being rendered from the first font containing it in the FontLink configuration.

Here's a preview on PowerShell Core

Actual behavior

Windows Terminal ignores FontLink configuration and renders characters as missing. Same session as in the expected behavior, using Windows Terminal:
