Android : Android Textview unable to display special characters?

I need to display data from sqlite with some special characters on it like for example,

myStr = "Testing123ʳ" (actual value is loaded from sqlite)

which contains a modifier letter small ʳ (U+02B3)

Refer to character info here http://graphemica.com/%CA%B3

I have tried

 1. myTextv.setText(Html.fromHtml(myStr))

 2. myTextv.setText("\u02B3")

 3. myTextv.setText(Html.fromHtml("ʳ"))

All doesn't work...
