Pro Sites Turkish Lira Sign Incorrect


I've just created a multisite network, and I'm planning to sell sites in TRY Turkish Liras. The symbol for Turkish Liras however seems to be wrong in Pro Sites.

The correct symbol should be HTML: ₺ (Unicode: U+20BA)
Pro Sites currently has the GBP Pound Sterling symbol, £

Can anybody point me to the file I need to modify to use the correct symbol?

Also I'd appreciate it if the Devs could correct this issue.

Best regards,
Burak Sepici

EDIT: The sign did not show up, so I decided to provide the HTML and Unicode equivalents of the symbol
