A few of the tests in the test suite assume a UTF-8 locale, so you're 
probably falling foul of that.  We could fix the tests - but we do want 
to test that the locale encoding is being respected in some way, so just 
adding hSetEncoding to those tests would be wrong.

Or you could just make those tests an expected failure on OpenBSD for 
the time being.

For the IO library, I expect you should default the encoding to Latin-1 
on OpenBSD.
