If only there was cut & paste, then I could send you all the emoji and you could save it!
Seriously though, emoji only works on my Softbank email account, not my Gmail. Also, if I send an emoji to a webmail account such as Gmail, the emoji only appears as the Softbank logo, a giant equals sign. Actually, I just sent one to my AU/KDDI cellphone and got the equals sign too
Maybe emoji is only Softbank to Softbank?
