Generating JSON like ICOMOON 
Is it possible to generate JSON like [`icomoon`](https://icomoon.io/app) does: [icomoon-tabler.json](https://github.com/user-attachments/files/17269739/icomoon-tabler.json)?

I've tried to import `.ttf` & `.json` generated by [`svgtofont`](https://github.com/jaywcjlove/svgtofont) ([here's the json](https://github.com/rahaaatul/kustom-tabler-icons/releases/download/v3.19.0/tabler-icons.json)) in [`KLWP`](https://play.google.com/store/apps/details?id=org.kustom.wallpaper) but it's crashing the app, but it does not crash if it's generated by [`icomoon`](https://icomoon.io/app).

Here's my [workflow file](https://github.com/rahaaatul/kustom-tabler-icons/blob/main/.github/workflows/manual.yml) where I'm using [`svgtofont`](https://github.com/jaywcjlove/svgtofont) at line `127`.

I'd really appreciate any help. Thank you.
