Strange character before £ sign with text?

I’ve been building a basic android app with processing and I’ve been trying to use the £ symbol a few times in my text but whenever it is displayed it has an extra character before? The symbol is an A with a small up arrow above it?
I’ve googled everything I can think of but with no luck, anyone got an idea?

It’s a character encoding issue. You need to specify UTF-8 somewhere. Depends where the text is - file or source code? I’ve seen this with websites - see eg.£-sign
