Allow aphricates in this RegEx
<p>We're using this regular expression to allow text only in input fields:</p>

<pre><code>/^[a-zA-Z-,]+(\s{0,1}[a-zA-Z-, ])*$/gi
</code></pre>

<p>Now, there's a problem since we're from Bosnia and we have special characters with aphricates, like:</p>

<pre><code>Č, Ć, Ž, Š, Đ
</code></pre>

<p>And their lower case variants, respectively:</p>

<pre><code>č, ć, ž, š, đ
</code></pre>

<p>How to add those in the regular expression above?</p>

<p><strong>Note:</strong> I am very low on my RegEx knowledge.</p>
