title: Text with "f" following "i", cannot see the dot on the "i", sans font
body: <p>I have a Button in which there is the text "Send files", but I cant see the dot on the top of the "i". I am using the default font (which is "sans", as far as I understand, but correct me if I am wrong).</p>
  
  <p>Here is the <code>xml</code> for my <code>Button</code> :</p>
  
  <pre><code>            &lt;Button
                  android:id="@+id/button_send_files"
                  android:layout_width="wrap_content"
                  android:layout_height="wrap_content"
                  android:layout_alignParentBottom="true"
                  android:layout_marginBottom="5dip"
                  android:padding="20dip"
                  android:text="Send files"
                  android:textColor="@color/black"
                  android:textSize="24sp"
                  android:textStyle="bold" /&gt;
  </code></pre>
  
  <p>If someone has some sort of trick to display the dot on the "i", it would be grea, because it's ugly as it is for now...</p>
  
  <p>I am using a Nexus 7, if it can help.</p>
