[web] Some of NotoSans KR glyphs are not fetched from google CDN after flutter 3.24.0 #188255
Description
Steps to reproduce
Run on web: flutter run -d chrome on the code sample
Expected results
Characters are displayed even if there are no fonts files provided, because there is ultimate flutter font fallback that should get notosans kr glyphs from fonts.google.com CDN.
Actual results
Characters are not fetched, tofu characters are displayed instead.
This happens only for small subset of NotoSansKR glyphs, most of them work correctly.
The only way to display notosans KR is to download and add to the project the font: https://fonts.google.com/noto/specimen/Noto+Sans+KR
the fallback doesn't work if local font covering the characters is not set:
THIS IS A REGRESSION, A BUG compared to flutter version 3.24.0. In flutter 3.24.0 fonts take long to fetch for the first time without cache, but eventually they are loaded:
Code sample
import 'package:flutter/material.dart';
void main() => runApp(const MyApp());
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
// 원 각 ꥠힰ
const text = '\u{110B}\u{116F}\u{11AB} '
'\u{1100}\u{1161}\u{11A8} '
'\u{A960}\u{D7B0}';
return MaterialApp(
home: Scaffold(
body: Center(
child: const Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [

);
}
