A custom font can be registered with the PDFFontsManager.registerFont function. When you set the cell's style as the customer font, SpreadJS will register that font when exporting to PDF.
Override the PDFFontsManager.fallbackFont function to provide a custom font file for the specific font string:

import * as ReactDOM from 'react-dom';
import './styles.css';
import { AppFunc } from './app-func';
// import { App } from './app-class';
// 1. Functional Component sample
ReactDOM.render(<AppFunc />, document.getElementById('app'));
// 2. Class Component sample
// ReactDOM.render(<App />, document.getElementById('app'));
