what is the emoticon that stands for Imoji?   ፷ ?

Didn't we have this visual language as kids - called comics?

And as far as I can ascertain, Katakana and Kanji are notoriously difficult to type on a qwerty keyboard.

I see Imoji as a fad much as flares and the bustle. Gone in an instance when true speach to text is perfected for noisey environs. And to return in spurts when there is money to be made from it.
