Wrap emojis with custom font

[stravag]

Older Android versions don't support all emojis, so it might be convenient to wrap emojis in a text with a font (ie. emojione) that supports all of them, without altering the overall look of the application.

The current solution to build the shortNameToUnicode map is terrible in my opinion. It might be wise to create a proper Android Library with the emoji_strategy.json embedded, and tests etc...

    @Test
    public void emojiWrapping() {

        SpannableStringBuilder mock = mock(SpannableStringBuilder.class);

        String text = "A\uD83D\uDC86B\uD83C\uDDE8\uD83C\uDDEDC\uD83D\uDC8FD";
        Emojione.wrapEmojis(text, Typeface.DEFAULT, mock);

        InOrder inOrder = inOrder(mock);
        inOrder.verify(mock).append(text);
        inOrder.verify(mock).setSpan(any(CustomTypeFaceSpan.class), eq(1), eq(3), eq(Spanned.SPAN_EXCLUSIVE_EXCLUSIVE));
        inOrder.verify(mock).setSpan(any(CustomTypeFaceSpan.class), eq(4), eq(8), eq(Spanned.SPAN_EXCLUSIVE_EXCLUSIVE));
        inOrder.verify(mock).setSpan(any(CustomTypeFaceSpan.class), eq(9), eq(11), eq(Spanned.SPAN_EXCLUSIVE_EXCLUSIVE));
        verifyNoMoreInteractions(mock);
    }

    @Test
    public void shortnameToUnicode() {

        String se = "\uD83C\uDDF8\uD83C\uDDEA";
        assertEquals(se, Emojione.shortnameToUnicode(":flag_se:", false));
    }

Thanks to the new emoji compatibility feature in the android support library this is no longer an issue: https://developer.android.com/guide/topics/ui/look-and-feel/emoji-compat.html
