Wrong currency symbol in emails

Hello,

I have set the default currency to USD. When I switch to other currency let say INR it goes perfectly. In the emails it shows price in INR(Rs) with the USD curreny($) symbol instead of ‘Rs’.

I did this : https://wordpress.org/support/topic/wrong-currency-in-the-mail-sent-to-customer?replies=4
but no effect

So can you please tell me any solution.
