Support UTF in Angular expressions

Currently the lexer in change detection uses StringWrapper.charCodeAt()

in Dart it returns s.codeUnitAt() which supports UTF
in JS it returns str.charCodeAt() which does not support UTF

the _Parser class in shim_css.js (shadow_dom_emulation) has the same limitation

This, I suppose, would allow things like

<div [class.u-1/2]="expr"></div>

right?

@pkozlowski-opensource I have a workaround for this:

https://stackblitz.com/edit/angular-ivy-zmtxmg?file=src%2Fapp%2Fapp.component.ts

import { Component, VERSION } from '@angular/core';

@Component({
  selector: 'my-app',
  template: '<div>{{ this["我的"] }} </div>',
})
export class AppComponent  {
  // Chinese character
  我的 = 'Angular';
}

I really wish Angular Team can take care of this issue. It's been 8 years since 2015.

It's embarrassing to see projects in 2024 that assume English as the only available language. Part of that unfinishing wish of cultural domination that some societies have.

The problem is especially challenging with third-party libraries when you don't have control over the data model. I understand that implementing this change isn't easy, but I'm hoping it will happen eventually.
