The error does not seem to be related to daru. It works fine on my computer. Looks like an iruby encoding issue.

Could you please try running the code on the command line and see if it still gives the error?

[kozo2]

I tried running the code on the command line.
Certainly it works fine on the command line.
I will submit this issue to iruby.
Thank you.
