Percent symbol problems

I have variables going into and out of a MySQL via PHP. The problem is that some of the text needs to include a percent symbol - %.

The varaibles are coming in like this:

&price1=£200&description1=100% Lambs Wool&price2=£300&description2=50% LambsWool

The percent sign is saved fine into the database but when Flash reads the above line of variables it obviously gets confused by the percent sign as the variables don’t load correctly when they are included.

Whats a way around this??
