Change specific character color in whole of the text
<p>There is a problem with a text which I want to change the colour of some characters like all of the stars. </p>

<p>My text is something like this: </p>

<pre><code>&lt;p&gt; Pedram Marandi * is a developer * He works at Foolanja. &lt;/p&gt;
</code></pre>

<p>I want to change the colour of * to red. </p>

<p>I've tried this code: </p>

<pre><code>  p:after {
    content: '*';
    color: red;
 }
</code></pre>

<p>But it seems this code will add a star after my p tag. 
How can I do this ? is it possible with only CSS ? </p>
