angular 6 custom material icons with ligature support

Is it possible to create custom material icons with ligature support. I am currently using svgIcon for getting Custom Icons, Is there any way to achieve ligature supported custom icons?

My current code snippet is given as below

app.component.ts

import { Component } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';
import { MatIconRegistry } from '@angular/material';

  @Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.scss']
  })
  export class AppComponent {
    title = 'app';

    constructor(
      iconRegistry: MatIconRegistry,
      sanitizer: DomSanitizer
    ) {
      iconRegistry.addSvgIcon('key',
        sanitizer.bypassSecurityTrustResourceUrl('assets/icons/key.svg')
      );
      iconRegistry.addSvgIcon('user',
        sanitizer.bypassSecurityTrustResourceUrl('assets/icons/user.svg')
      );
    }

  }

login.component.html

<mat-form-field>
  <input matInput placeholder="Username" formControlName="username">
  <mat-icon matPrefix svgIcon="user"></mat-icon>
  <mat-error *ngIf="username.invalid">Username is required</mat-error>
</mat-form-field>

<mat-form-field>
  <input matInput type="password" placeholder="Password" formControlName="password">
  <mat-icon matPrefix svgIcon="key"></mat-icon>
  <mat-error *ngIf="password.invalid">Password is required</mat-error>
</mat-form-field>

Sure its possible:

Step 1) Get all the SVG icons.

Step 2) Create your font with a custom ligature.

This is a tool, to create your own font library with ligature support. https://icomoon.io

Step 3:

Declare your own font.

@font-face {
  font-family: 'icomoon';
  src: url('path.ttf') format('truetype');
  font-weight: normal;
  font-style: normal;
}

Step 4: Override the .material-icons with you own font

.material-icons {
  font-family: 'MyFontFamily';
   ...
}

or declare your own fontSet so you can work with both.

// Register to AppComponent

 constructor(iconRegistry: MatIconRegistry) {
    iconRegistry.registerFontClassAlias('MyFontFamily', 'MyIconClass');
 }

Last step.

<mat-icon>LigatureToDisplay</mat-icon>

OR

<mat-icon fontSet="MyIconClass">LigatureOrUnicodeToDisplay</mat-icon>
