How to use tick / checkmark symbol (✓) instead of bullets in unordered list?

I have a list where I want to add tick symbol before list text. Is there any CSS that can help me to apply this way?

✓ this is my text
✓ this is my text
✓ this is my text
✓ this is my text
✓ this is my text
✓ this is my text

Note: I want this in this type of HTML code

<ul>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
</ul>

You can use a pseudo-element to insert that character before each list item:

ul {
  list-style: none;
}

ul li:before {
  content: '✓';
}
<ul>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
</ul>

Here are three different checkmark styles you can use:

ul:first-child  li:before { content:"\2713\0020"; }  /* OR */
ul:nth-child(2) li:before { content:"\2714\0020"; }  /* OR */
ul:last-child   li:before { content:"\2611\0020"; }
ul { list-style-type: none; }
<ul>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
</ul>

<ul>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
</ul>

<ul><!-- not working on Stack snippet; check fiddle demo -->
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
</ul>
