I heard that when you type the term siigit into Fargo you get a weird Emoji character.
That's six hyphen digit.
Let's see if it happens here.
We're using Emojify in Fargo to do the rendering.
One thing you can do until we figure out what's going wrong is you can turn Emoji's off globally or on a single page. See the announcement page for Fargo 1.60 to see how to do it.
Perhaps this should be reported as an issue on the GitHub project?
I added a comment to a reported issue that says that'd gets screwed up in a similar way.
