Problem with Spannable
I try to use IconicsTextView with this:

```
val spannable = SpannableString("{gmi-pin} my text bla bla bla")
spannable.setSpan(ForegroundColorSpan(Color.MAGENTA), 0, 10, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
mytextView.Text = spannable

```
but the Magenta Color does not appear.
If I change the TextView color for all text without spannable it work.
