Hey Flavio, thanks for the PR! Please add Android parity, docs, unit-tests and example-code for your PR, thx!
Flavio De Stefano 2016-10-28

I'll address today. But, there's no Android parity, cause AttributedString are missing on Android. Right?
Hans Knöchel 2016-10-28

Ti.UI.AttributedString is cross-platform.
Flavio De Stefano 2016-10-28

Oh, I didn't notices that, sorry :) I'll indagate on how to implement in Android. Thank you.

Demo:

   var win = Titanium.UI.createWindow({
       backgroundColor: '#ddd',
   });
   
   win.open();
   
   var text = 'Bacon ipsum dolor Appcelerator Titanium rocks! sit amet fatback leberkas salami sausage tongue strip steak.';
   
   var attr = Titanium.UI.createAttributedString({
       text: text,
       attributes: [
           // Sets the line height
           {
               type: Titanium.UI.ATTRIBUTE_LINE_HEIGHT,
               range: [0, text.length],
               value: 20.0
           },
       ]
   });
   
   var label = Titanium.UI.createLabel({
       width: 200,
       height: Titanium.UI.SIZE,
       attributedString: attr
   });
   
   win.add(label);

Moving out of 6.2.0, since we are trying to finalize the version the upcoming weeks and the PR has outstanding code-review adjustments.
