unicode emoji in messages

[Matt Price]

What do other people use to view(and potentially compose) unicode emoji in messages? I've started getting these lately and it would be convenient to be able to see them directly in emacs. 

Thanks!

Well, if they're Unicode emoji, then all you really need is a font
that covers them. If you don't want to use that particular font
for the rest of your Emacs, you'll need to it set up in such a way
that it gets used for those emoji only. I know Emacs can do this
using so-called fontsets, but I'm not entirely sure how.

As for inputting them, you can always use C-x 8 RET, but if you
intend to do this a lot, you may want to look into defining a
custom input method, which is fairly straightforward. For example,
this is what I use to create an input method for inputting some
common semantic symbols (view with an appropriate Unicode font):

```
(quail-define-package
"semantics" "Sem" "Sem" t
"Input method for semantics notation."
nil t nil nil nil nil nil nil nil nil t)

(quail-define-rules
("[[" ?⟦)
("]]" ?⟧)
(".^" ?∩)
(".v" ?∪)
(".<" ?⊆)
("/=" ?≠)
("/o" ?∅)
("+o" ?⊕)
(".e" ?∈)
("/e" ?∉)
("^w" ?ʷ)
(".N" ?ℕ))
```

Strangely enough, `quail-define-rules` doesn't have an argument
telling it which quail package to add the rules to. You just need
to put the package definition right before the rule definition.

An alternative way to input them would be to use the hydra package
and define a hydra for them.

To view UTF-8 emoticons (while my default font is not DajaVu), I use
        (set-fontset-font t '(#x1F600 . #x1F64F) "DejaVu Sans")

Hope it helps,
