Error: ArgumentError; message invalid byte sequence in US-ASCII. Failed evaluating erb template for section report and template

When I run metric_fu with ANY metrics enabled I always get following error

This doesn't happen if I disable all the metrics (with --no-...) or change format to yaml.

Are you able to install from the read_report_in_binary branch? Or produce a failing test?

[mszyndel]

When I tried to install this branch I got US-ASCII error from Bundler. After some googling it turns out, that it's Mac-specific problem and can be solved by exporting this to env:
LANG=en_US.UTF-8
LC_ALL=en_US.UTF-8

Now I can install and run gem without any problems.
Maybe it would be nice to add an info for Mac users after installation (or maybe even only when those env vars are not set?)

[bf4]

Oh, weird. I thought it might be some external encoding thing. This should probably go in an FAQ. Would you mind updating the wiki? (I tried writing some tests for this but was unable to duplicate).
