Please don't use emoji in passwords until UTF-128 comes out.
Half of its code points (2 ^ 64) will be characters whose glyphs are every possible combination of 8x8 bit images. That way you can make monochrome graphics simply with rows and rows of adjacent characters in the enormous sized UTF-128 font.
And imagine how many emojis there will be? There would more than one emoji for every human who has ever lived.
In short, we'll have really safe passwords using characters from UTF-128. So be patient. ;-)
