That's bothersome.
Would you agree that the url encoding must be done on octets? If so,
then I think it would be correct to issue a warning if the utf8 flag
is on.
I think doing it in query_form would be the best place as it tells the
user what specific item had the utf8 flag on.
while (my($key,$vals) = splice(@new, 0, 2)) {
$key = '' unless defined $key;
warn "key [$key] has utf8 flag set and may not url-encode"
if utf8::is_utf8( $key );
$key =~ s/([;\/?:@&=+,\$\[\]%])/$URI::Escape::escapes{$1}/g;
$key =~ s/ /+/g;
$vals = [ref($vals) eq "ARRAY" ? @$vals : $vals];
for my $val (@$vals) {
$val = '' unless defined $val;
warn "value [$val] for key [$key] has utf8 flag set and may not url-encode"
if utf8::is_utf8( $val );
$val =~ s/([;\/?:@&=+,\$\[\]%])/$URI::Escape::escapes{$1}/g;
Actually, I guess I'd argue to die, but that might break existing
code. After all, if trying to url-encode characters might result in
dropped or altered data that's pretty serious.
