I know the whole "changing the currency type" problem crops up repeatedly throughout the forums, but I'm having a slightly different problem.

Changing the '£' to '£' does fix the problem, except on the checkout page, where it appears as £ rather than the £ symbol.
I guess that the former problem is an encoding issue. How could I fix it? Thanks
