notify-via-isms: URL encode when % is on the end of message - message sending fails

[kucert]

My solution:

sub urlencode {
my $str = "@_";
$str =~ s/%([A-Fa-f\d]{2})/chr hex $1/eg; # decode first, there are new lines encoded by checkmk
$str =~ s/([^^A-Za-z0-9\-_.~])/ sprintf "%%%02X", ord $1 /eg; # encode also % character !!!
return $str;
}
