CurrencyToStrF not giving correct symbol in windows

[trebor]

Hi,
I am having trouble with CurrencyToStrF.
It does not give the correct symbol for GBP (£) while in Windows XP, although it seems to work properly in Linux.
It shows as a ?, I am fairly certain it is not a font issue as printing a £ manually works fine, and it seems to be only with strings returned from CurrencyToStrF.

Also does anyone know how to set the currency format to a specific area?

Any help would be much appreciated.
