Netbeans not displaying UTF8 unicode characters (emoticons) correctly
<p>I've been unable to get these characters to display within code (or a plain <code>.txt</code> file) in Netbeans. </p>

<p><code>✰☆★☞☛❸➂❤♡✉</code></p>

<p>Instead, they apprear as white squares like these: </p>

<p><code>☐☐☐☐☐☐☐☐☐☐☐☐☐☐☐☐☐☐☐☐☐</code></p>

<p>I'm using Netbeans IDE 8.0.2. I've already set <code>-J-Dfile.encoding=UTF-8</code> in <code>../etc/netbeans.conf</code>. In my project's properties, I've set <code>Encoding : UTF-8</code>. Tools > Options > Fonts &amp; Colors > Default > Font > Courier New 13.</p>

<p>Interestingly, when I open <em>the same text file</em> using Notepad++ 6.9 (and using "Courier New" font), I can see all of those characters fine!  Microsoft Word also displays them correctly.</p>

<p>I'm on Windows 10.</p>

<p>Two other interesting notes: </p>

<ul>
<li>A different kind of heart character (<code>♥</code>) <em>does</em> work in Netbeans IDE 8.0.2 using Courier New 13.</li>
<li>Changing to fonts other than Courier New 13 (in Netbeans) can sometimes lead to <em>some</em> of the characters displaying correctly.  

<ul>
<li>But I'd really like to continue to use Courier New 13 in Netbeans, and I want to fix Netbeans so that it correctly displays all of these characters (as Notepad++ and other programs already do).</li>
</ul></li>
