Email Templates - Currency Symbol Not Displaying / Location

[drop$hipper]

Hi all,

My first post on here

I'm having a problem with the £ sign in my confirmation emails becoming a diamond with a ? in it.
See my screenshot attachment for details - it happens when you don't use £ in place of a £.

Does anyone know where to find the list of currency symbols / where they are located in the file structure?
Or is this a bootstrap thing?
In the email template in the front end we just have two td elements with the handle {{price}} (e.g. below).

Anyone know where this points?

<td align="left" style="color: #444;font-size: 14px;line-height: 24px;">Price:</td>
<td align="right" style="color: #444;font-size: 14px;line-height: 24px;">{{price}}</td>

Thanks!
