This is using the Git for Windows bash, but it might be worthwhile in any case to try to detect support or use a different character (tested with o, that works fine and looks worse-but-not-awful).

Are you using this through the command prompt or through the fancy new WSL beta terminal?

Neither, exactly, though I assume there are other real terminals that don't support unicode.

Edit: The terminal is based on msys2 which is based on cygwin, and it comes with what you get when you install "Git for Windows". I'm actually using that through a different terminal utility but was able to reproduce it in the regular one, so I didn't want to confuse the issue.

I found a way to detect support for unicode but my knowledge of Haskell is super limited so I didn't get it working.

Decided to fix this by dropping the fancy symbol and using a lowercase "o". Keeping it old school. 76e749ee648473ab47655e0b25c9fe52b7b10ce2
