I am using this code to display rupee symbol. 

```
&#x20B9 ; // semicolon is just after 9.

```

for example

```
<td> &#x20B9;{{ od.quantity * od.product_sell_price | currency:""}}</td>

```

But it is displaying empty box instead of rupee symbol in some machines/browsers. For me it is displaying proper but some people shared me screen shot where it is a kind of empty rectangle box.

Can anyone help me why is that different behavior and how to fix it?
