title: display multiline/multiple characters as key label on soft keyboard keys
body: <p>Hi i am working on <strong>android soft keyboard</strong>. Normally labels displayed on
  keys are single character as shown below</p>
  
  <p><img src="https://i.stack.imgur.com/Y1wrr.png" alt="enter image description here"></p>
  
  <p>the above one is <strong>done by</strong> just using <strong>keylabel</strong> attribute of Key tag in Keyboard
  to display whatever text we want on the key. But now my requirement is to display multiple characters on single key as shown below</p>
  
  <p><img src="https://i.stack.imgur.com/eqAz7.png" alt="enter image description here"></p>
  
  <p>I got one solution to this by using <strong>android:keyIcon</strong> but limitation is I need the color of characters to be configurable so that a user can change color of any character. Like <strong>1 with red, | with blue, q with green</strong>. So it must be configurable to any color.That's why I skipped keyIcon property for displaying text on character.</p>
  
  <p>So is there any way to set multiple characters on key.</p>
