Nerd Font ligatures not rendering correctly

My `config.yml` includes:

```
fontFamily: "JetBrains Mono"
```

And when I `fc-list : family | grep JetBrains` it returns an installed font, which is also active in my terminal:


But when I record and render a file, the render includes missing characters in the prompt line:

```
terminalizer record testDemo --config ./config.yml
terminalizer render testDemo.yml
```


Reproduce the issue with the shown config.yml and the JetBrains Mono font, using terminalizer record testDemo --config ./config.yml followed by terminalizer render testDemo.yml. Trace how the configured font is handled during recording and rendering; done means the rendered prompt displays the ligatures and characters correctly.
