[Bug] Incorrect behavior when template contains a

[HeroicEric]

🐞 Describe the Bug

Components are not formatted correctly when <template> contains unicode characters such as ✓ or © rather than ✓ or ©.

🔬 Minimal Reproduction

Failing test added in https://github.com/gitKrystan/prettier-plugin-ember-template-tag/pull/221

import Component from '@glimmer/component';

export interface Signature {
  Element: HTMLElement,
  Args: {}
  Yields: []
}

/** It's a component */
class MyComponent extends Component<Signature> {
  <template>
    ✓
  </template>
}

function hello() {
  return 'Hello';
}

function world() {
  return 'World';
}

😕 Actual Behavior

import Component from "@glimmer/component";

export interface Signature {
  Element: HTMLElement;
  Args: {};
  Yields: [];
}

/** It's a component */
class MyComponent extends Component<Signature> {
  <template>✓</template>
}
function hello() {
  return "Hello";
}
function world() {
  return "World";
}

Note: The newlines are removed between the helper functions.

🤔 Expected Behavior

import Component from "@glimmer/component";

export interface Signature {
  Element: HTMLElement;
  Args: {};
  Yields: [];
}

/** It's a component */
class MyComponent extends Component<Signature> {
  <template>✓</template>
}

function hello() {
  return "Hello";
}

function world() {
  return "World";
}

🌍 Environment

• prettier-plugin-ember-template-tag version: 2.0.0
• ember-template-imports version (if applicable): 4.0.0
• content-tag version (if applicable): 1.2.2
• eslint-plugin-ember version (if applicable): 12.0.0-alpha.4

➕ Additional Context

Replacing the direct symbols with the HTML entity codes like ✓ fixes the formatting issue (and is preferred anyway)
