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
```
It seems that using the patched version from [here](https://github.com/ryanoasis/nerd-fonts/releases/) seems to work without issues, when you supply `fontFamily: "JetBrainsMono Nerd Font Mono"`
I borrowed this from the instructions over at [asciinema](https://docs.asciinema.org/manual/agg/usage/) (which seems to be more actively maintained than this repository anyway, so I might just switch over to that, if anyone else happens to find this issue).
