In my environment, User-Agent: strings is always
Mozilla/4.0 (compatible; MSIE 5.5; Windows 98; Win 9x 4.90)
It seems to be independent with whether that setting is enables.
The problem is, even if we enable the setting, MSIE sometimes sends
corrupted UTF-8 string. In my environment, delimiting dots in
domain names are corrupted as UTF-8.

Agree. Or you should overload encode() easily, if you know how to
translate local encodings which your browser uses, to UTF8.

Already done :-) Here's an excerpt from ACEProxy.pm.
# Encode hostname to ACE
my $uri = URI->new($r->uri);
my $ace_host;
eval {
$ace_host = join '.', map {
# RFC 1035: letter, digit, hyphen
/^[\x30-\x39\x41-\x5a\x61-\x7a\x2d]*$/ ?
$_ : $class->encode($_);
} split /\./, $uri->host;
};
if ($@) {
(my $exception = $@) =~ s/ at .*$//; chomp $exception;
require Apache::Log;
$r->log->error("Apache::ACEProxy: error happens while ACE conversion: $exc
eption");
return;
}
