}

What do you see instead?

}

Something about the interaction between Emacs and gofmt seems to be stripping the
unicode out. If I run gofmt directly from the command line, everything's fine.

I think I have a fix in http://golang.org/cl/4532057/
Please try patching it in to see if it fixed the problem in your environment.  It works
for me with your example code on MacOS.

Yep, that did it. It's fixed for M-x gofmt and gofmt-before-save.

Cool.  FYI the fix moved to http://golang.org/cl/4523065/ (but it's the same
change)
