This translator generates superscript (ˢᵘᵖᵉʳˢᶜʳᶦᵖᵗ) which you can copy and paste. It is actually converting your text into a subset of the Unicode standard. This is why you're able to copy and paste it around the place (e.g. facebook, tumblr, twitter, reddit, instagram etc.). It's also useful for generating exponents, for example if you're trying to submit an equation somewhere LaTeX and other formatting isn't supported.
