title: What are some good fonts for User Interfaces? And what about Unicode?
body: <p>I am working on a user interface, and I am wondering what fonts do other software use like Photoshop, Windows, etc use in their interface. They can't be using Arial and Tahoma, right? This is a web application I am working on, and I can use @font-face.</p>
  
  <p>But what about Unicode support? I would not like to put any limits on i18n.</p>
