get hebrew chars from textbox asp.net
<p>So, </p>

<p>ive got a textbox in my website, which is writeig in c# asp.net 4. </p>

<pre><code>&lt;td&gt;
    &lt;asp:TextBox ID="UserName" runat="server" CssClass="textEntry" Width="265px" 
     placeholder="שם משתמש" ontextchanged="UserName_TextChanged"&gt;&lt;/asp:TextBox&gt;
&lt;/td&gt;
</code></pre>

<p>the problem is, that when someone trying to put hebrew input its lets him do it. </p>

<p>how can i know that the input he is trying to write is hebrew and dont let him? just like show him a warring in javasciprt, or just dont let him. </p>

<p>any one can give me a hand?</p>

<p>thanks!</p>
