Disappearing Currency Text - £

[LeeOvEngland]

I have a small web application that allows a user to enter a description into a textbox. The description looks something like this: 'The car is blue and costs £5,000. What a bargain.' When the user presses submit the value entered into the textbox is assigned to a string. Once the page has reloaded the '£' symbol has disappeared. I have tried it with other currency symbols and they work fine. Please can somebody tell me why the '£' symbol does not assign to the string and if there is a work around. Thank You
