Average time computation just prints out "10??"

I guess that's an improvement. I still can't read it in my text editor, but
I can paste it into my browser and see what it was supposed to be
printing.  This produces a text line like this:
-----------------
# Warmup Iteration   1: ≈ 10⁻⁵ s/op
-----------------

Why did the JMH implementors decide to introduce the complexity of unicode
into this?  This should be simple textual information.  I shouldn't have to
work this hard to get this.
