SourceKitten not happy with 🍒 emoji

[Mozahler]

It took me way too long to find out why my project wouldn't compile. I have emoji in other files, and they don't cause this:
Parsing Dummy.swift (24/25)

'

I extracted the crucial code and attached it. This file causes the above error. (I have moved on by deleting the 🍒 ) Please let me know if I should have reported this in the SourceKitten repository. I put it here because I was running jazzy.

It turns out I have another file which causes a different error, but I believe it is related (it has many cherries in it). All 24 files are parsed without errors, and then I get a pile of them:

I've attached the file without cleanup (it is a couple of years old, the only changes have been to get it to compile with language updates along the way 🙄)

The latest version of sourcekitten has no problem with this file. The version of sourcekitten included with jazzy does crash as you've discovered. Looks like jpsim/SourceKitten#350.

[Mozahler]

Great news. Thanks.

Let's keep this open until jazzy itself has the fix. I'm updating jazzy's SourceKitten binary now.
