[Windows] App Crashes when path contains non-latin characters

[jihoobyeon]

I made a simple React Native for Windows app for practice, which write a sentence of plain text and read that file to show the content at window.
this is my App.ts:

import { Component, createElement } from 'react';
import { Text } from 'react-native';
import { readFile, writeFile } from 'react-native-fs';

class FileIO {
	protected path = 'C:\\Users\\변지후\\Desktop\\';

	constructor(file_name: string) {
		this.path += file_name;
	}

	public read() {
		return readFile(this.path)
			.then(content => {
				return content;
			})
			.catch(e => {
				console.log(e.code + ':\t' + e.message);
			});
	}

	public write(file_content: string) {
		writeFile(this.path, file_content)
			.catch(e => {
				console.log(e.code + ':\t' + e.message);
			});
	}
}

export default class App extends Component<undefined, { str: string }> {
	constructor(props: any) {
		super(props);
		this.state = { str: '' };
	}

	protected io = new FileIO('test.txt');

	async componentDidMount() {
		this.io.write('The quick brown fox jumps over the lazy dog.\n');
		const file_str = await this.io.read();
		this.setState({ str: file_str });
	}

	render() {
		return createElement(Text, undefined, this.state.str);
	}
}

but when I run this app, the UWP window appears, but disappears before contents being rendered.
there are NO error message at Debugger UI.

note: this is my result of npx react-native info:

Hi, how did you manage to link react-native-fs library to the project ?

Actually, I used @avmoroz 's fork. I knew it from here.
sadly for me, profile of @avmoroz says he/she hasn't contributed anything on Github a year, so I'm asking here.

@jihoobyeon Can you try if it works with the following fork + branch: https://github.com/wwimmo/react-native-fs/tree/fixUmlautePaths ?
