How to change currency sign into different symbol

If we have to change the currency sign or have to put different currency sign there. Then we can use this method there for getting the values.

<#if record.currencysymbol = 'GBP'>
      <#assign currencyType = '£'>
</#if>

After assigning the currency just call it before the value where we want to put. For Eg: ${currencyType}
