andrew-tpz · 2021-11-25T08:00:00Z

Unable to load assets with "ё" or "й" characters in path on iOS. The same assets are successfully loaded on Android.
Unit-test passed on Windows, but failed on MacOS, All other cyrillc characters can be used without error.

Steps to Reproduce

Create new flutter project
Create text asset 'assets/data/ё.txt' with 'ok' text in it
include asset in pubspec.yml

  assets:
    - assets/data/

Create unit-test test/asset_test.dart

import 'package:flutter/services.dart';
import 'package:flutter_test/flutter_test.dart';

void main() {
  TestWidgetsFlutterBinding.ensureInitialized();
    test('Check ё', () async {
      expect(await rootBundle.loadString('assets/data/ё.txt'), 'ok');
    });
  });
}

Execute flutter test on MacOS

Expected results:
Test passed

Actual results:
Test failed with error: unable to load asset

MacOS: BigSur
XCode: 12.4
Flutter: 2.5.3 stable

Code sample

Sample project to reproduce with app on iOS or with unit-test on MacOS:

Hi @andrew-tpz, Thanks for filing the issue. I am able to reproduce the issue, With the Cyrillic character. The PlatformAssetBundle.load fails to load the asset. But this works on Windows looks like this is specific to macOS platform.
