[MlMt] smart mailbox to select emojis

[John Doherty]

I'd like to create a smart mailbox that selects messages whose subjects 
include emojis.

I don't think it's possible to use regular expression character classes 
in a "subject contains" condition, but if it were, I think something 
like this would be a pretty good start:

subject contains [^[:alnum:][:punct:] ]

That would potentially catch a lot of things that aren't actually emojis 
but my sense is that in my mail there are not actually a lot of other 
things to catch. It may be, for example, that I have more mail than I 
think with, say, accented characters or copyright symbols in their 
subjects, but I doubt it.

Any ideas? Thanks.
