Unable to Render Glyphs in GHA Context

[osterman]

Problem

Specific glyphs (e.g. ⧉ ✗ ⨠) do not render using any of the Nerd Fonts that I've tried. The Glyphs render in the terminal output (stdout) of the GHA, but not in the rendered Gif.

Here's an example of a corresponding run that generated it: (See Job Summary)

https://github.com/cloudposse/demo-vhs/actions/runs/7290247606#summary-19866608928

Setting the following environment in the workflow has no effect on the outcome.

  TERM: "xterm-256color"
  COLORTERM: "truecolor"
  LANG: "en_US.UTF-8"

Expected Output

Here's what I get on my Mac, by running make demo.

Note, that the output from vhs in the job is correct:

Reproduction

Here's how to reproduce it locally.

Clone https://github.com/cloudposse/demo-vhs

Then run make demo.

This produces the expected output on my Mac, but not in the GitHub Action using the official vhs-action.

Did you set the font family? I set this:

Set FontFamily "JetBrainsMono Nerd Font"

And my lsd output shows the symbols
