Is it possible to add to angular material label in form that allows user enter screenshoots and html characters to label form?

<p>
  <mat-form-field appearance="legacy">
    <input matInput placeholder="Subject" />
    <mat-icon matSuffix>sentiment_very_satisfied</mat-icon>
    <mat-hint>Hint</mat-hint>
  </mat-form-field>
</p>

<p>
  <mat-form-field appearance="legacy">
    <input matInput placeholder="body" />
    <mat-icon matSuffix>sentiment_very_satisfied</mat-icon>
    <mat-hint>Hint</mat-hint>
  </mat-form-field>
</p>

Thank you in advance
