&gt;What about non-alphabetic written languages?<p>Some English words can already be writen without using the alphabet. For example, &#x27;2015&#x27;. I believe numerals in English are used exactly as emoji (or Chinese characters) in Japanese now: embedded inside the sentences, which are composed according to the grammar of language.<p>&gt;The input difficulties of emoji today seems temporary.<p>It depends on language, in Japanese input methods a lot of emoji can be written exactly the same way you write rest words.
