title: sms text encoding
body: <p>All I'm asking is if SMS messages on Windows Phone 7.x are encoded in ASCII or UNICODE format, and in particular, which type. </p>
  
  <p>Practically, I want to convert a string containing greek characters, which the user has typed in a textbox, to a string containing -among other chars- the respective uppercase greek characters, so that the sms will not be limited to have 70 characters only!</p>
