Hmm. I have Cygwin v1.7 (on Windows 7 and Windows 2003 Server R2)
with many locales installed (and with en_US.UTF-8 locale, too)
Today I could not find a way to run tests with "no en_US.UTF-8 locale
installed" simulation
to test your failure

Hmm, for me all these tests pass on both Linux and Cygwin (mentioned
above) boxes

Yep, thanks for your correction

You're right (I've looked at explanation in
3994e8a98dc7bbf67e61d23c8125f44383499a1f; I've thought ISO-8859-1 is a
common name).

I've changed tests. I've reverted back these ones, and added
new ones with no i18n.commitEncoding set

These encodings "have appeared" because we've changed 'setup':
we make commits with i18n.commitEncoding set
