One shouldn't use str() as that then depends on system encoding, which can
trust. You should use encode() method of Unicode string explicitly.
output.encode('UTF-8')
The encoding should actually be what every encoding the content type response
header said was being used.

The one that worried me is:
('locale.getpreferredencoding()', 'ANSI_X3.4-1968')
I really don't understand exactly how some of those get set and what they are
meant to indicate. It is entirely possible that my attempts to override them
are wrong.
if (daemon->group->lang) {
char *envvar = apr_pstrcat(p, "LANG=", daemon->group->lang, NULL);
ap_log_error(APLOG_MARK, APLOG_DEBUG, 0, wsgi_server,
"mod_wsgi (pid=%d): Setting lang to %s.",
getpid(), daemon->group->lang);
putenv(envvar);
}
if (daemon->group->locale) {
ap_log_error(APLOG_MARK, APLOG_DEBUG, 0, wsgi_server,
"mod_wsgi (pid=%d): Setting locale to %s.",
getpid(), daemon->group->locale);
setlocale(LC_ALL, daemon->group->locale);
}
So 'LANG' is set by setting the environment variable, but locale is set by
using setlocale() as it is already set by C libraries from LC_ALL environment
variable.
I can't remember why I though that setting LANG environment variable was
enough. Right now doing that doesn't seem right.
Just so have full context, can you provide the full WSGIDaemonProcess directive
line so can see everything that is being set.
Thanks.
