Default Framework for no mms emoji?

Hi,

I got a I9506 and no custom roms exist yet. There are also no deodexed 4.3 roms. I would like to stay on stock messenging app.
Therefore I would like to know if there is a framework that prevents mms conversion when inserting an emoji in stock app.

Thanks.
