Contributor guide

Research direction
Investigate the Android renderer for Label, specifically the handling of LineBreakMode.CharacterWrap. Compare the implementation with iOS to identify the difference. Look at the Xamarin.Forms source code in Xamarin.Forms.Platform.Android/ViewRenderer.cs and related files. The fix might involve setting the appropriate BreakStrategy or HyphenationFrequency on the native TextView.
