Custom Pricing setting is using the wrong currency symbol

The Custom Pricing setting is showing the $ symbol, can I show yen or another currency symbol?

The dollar symbol ($) is only displayed inside of the Custom Pricing admin. On the storefront, the price is shown in your store's default currency.  For example, if you enter a fixed price of $2000 and your store's currency is in yen, the price would display as ¥2000 for tagged users.
