Slugified emoji turns out as an empty string

[Betree]

Hi, thanks for this awesome library!

We've faced a situation with strings only made of emojis.

Actual behavior

limax('😵️') === ''

Expected behavior

// Replace by emoji name
limax('😵️') === 'dizzy_face'

// Or by emoji code (as when pasted as an URL in the browser)
limax('😵️') === 'xn--w38h'

Hi, did you see #31?

Hi @lovell, thanks for the reference. Don't you think that would be a nice addition to limax core?

Yes, happy to accept a PR if you're able.
