Arabic support

Actually, it looks like the default item renderers for Spark data containers are using FTE/TLF. I don't know Arabic, so I'm not entirely sure these words are rendered correctly (or whether I even copied them correctly), but the item renderers are consistent with the Spark RichText component.
