title: SQL Server, how to set the default collation to unicode?
body: <p>I've a WPF+WCF application which works good for now 2 years, but now they have one needs: They want to enter some data in the database, which isn't in the european alphabet(e.g. cyrillic).</p>
  
  <p>The problem is that the database as a collation set to Latin1_General_CI_AS_WS, and when I store data in it(e.g. вмешательство), and retrieve them, I got some "??????" instead(When going in the SQL Server Management studio).</p>
  
  <p>The rest of the application already knows working with other kind of alphabet(not for direction of reading, but not my direct problem).</p>
  
  <p>So how can I set the collation to unicode, in an existing database? The collation field is in gray in the SQL Server management studio.</p>
  
  <p>I'm using EntityFramework for all my communication with the database, and I also got those "????" if I retrieve any fields.</p>
