Switch between Text and Icon
How can i switch between a letter and a registered unicode, and keep the font size?

I do register the fonts on App level:

``` java
GenericFont genericFont = new GenericFont("abc", "fonts/"+FONT_FILENAME);
genericFont.registerIcon("option_01", '\ue904');
Iconics.registerFont(genericFont);
```

Then i have on layout (XML):

``` xml
<com.mikepenz.iconics.view.IconicsTextView
            android:id="@+id/letter"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:textSize="24sp"
            android:background="#0000FF"
            android:textColor="#FF0000"
            />
```

Now i need to switch between letter "A" and "{abc-option01}". To be more precise i need to keep the font size and switch colors (background and textColor):

State1:
Text: "A"
Font Size: 24sp (does not change)
Background: #0000FF
Text Color: #FF0000

State 2:
Text: "{abc-option01}"
Font Size: 24sp (does not change)
Background: #FF0000
Text Color: #0000FF

How can i accomplish this? The font size seems to change when it switched to unicode.
