VAT Question

94 0 11

I've been using Shopify since April last year! I'm not at the moment VAT registered but it looks like that's about to change. As I'm in the UK, UK customer will pay the VAT but customers outside won't how does Shopify handle this? Is it straight forward to implement so that my customer outside the UK will have the VAT deducted from what they pay?  

Also I sell digital download knitting patterns among other things, do downloadable products include VAT?
