I forked the Metabase-Fact repository, locally cloned, added this repo ('dagolden') as upstream, then fetched this p.r. with:

git fetch upstream pull/10/head:hakonhagland-utf_support-10

... and checked out the hakonhagland-utf_support-10 branch locally.

I then called perl Makefile.PL && make && make test -- I haven't yet bothered with all the Dist-Zilla-related stuff -- and got one test failure:

$ prove -lv t/user/profile.t

@hakonhagland, can you investigate and add tests as needed? We need to demonstrate that your p.r. will do no harm. Thanks.

can you investigate and add tests as needed?

@jkeenan Think I just forgot to import the Encode module, see added commit.

I'm not actively working on anything related to CPAN testers. I've asked preaction to add me back to the cpan-testers org so I can transfer this and anything else CT related there so others can maintain it.
