I can't explain that.  In both cases, getent calls setlocale(LC_ALL, "").
In both cases, the account information comes as UTF-16 string from
the OS and is converted to multibyte in Cygwin.

The only (vague) idea I have is that this may be a result of caching.
If the first account ("authenticated users") has been fetched while
LANG was still set to "C" or "C.UTF-8", it would explain this
discrepancy.

Which shows that using non UTF-8 locales is not such a good idea.  There
is a chicken-egg problem.  Early initialization always uses UTF-8 for
hopefully obvious reasons.  Using UTF-8 in all multibyte scenarios is
really the way to go in future.
