Hello.

Can you do this ? or not ?

1. Paste the function below into your script.
2. This will ouput encoding information of $ARGV[0] to logfile.txt

troubled_string($ARGV[0], "logfile.txt");
3. Examine logfile.txt with your browser, and find normal string, changing "Encodings" of your browser.
sub troubled_string{ my ($str,$logfile_path)=@_; use Encode qw(decode encode from_to encodings); open (my $fh, ">", $logfile_path) or die $!; printf $fh "utf8 flag:%s\n",utf8::is_utf8($str) ? "utf8 flagged" : + "not utf8 flagged"; printf $fh "hexdump:[%s]\n",utf8::is_utf8($str) ? unpack('U0H*', $ +str):unpack('H*', $s tr); printf $fh "length:[%s]\n", length($str); printf $fh "%s\n", "-" x 20; if ( utf8::is_utf8($str) ){ printf $fh "[encode trial]\n"; printf $fh "%-25s:%s\n",$_,encode($_, $str) for (Encode->encod +ings(":all")); } else { printf $fh "[decode -> encode trial]\n"; printf $fh "%-25s:%s\n",$_,encode($_, decode($_,$str)) for (En +code->encodings(":all")); } close $logfile_path; }

[Lady_Aleena]: My biggest problem with hashes at the moment is one with 2,501 keys.
[choroba]: how many event types are there?
[Corion]: Also I found that I can't conveniently weaken an array slot, which also is inconvenient, as I want my one-shots to disappear if the caller discards them
[Corion]: choroba: Currently two or three that my program handles (WWW::Mechanize:: Chrome), but there might be more that become interesting
[Corion]: But I don't expect more than 100 to be active at the same time, so I'm not really sure if there is a not-too-fancy data structure that is maintained with few lines of code where the performance is better than the linear scan ;)
[Corion]: But I should do a mock-up program so that others can see what I'm talking about ;)
[robby_dobby]: Corion: I hope you know all too well that passing around "fancy" datastructures is a recipe for disaster :-)
[robby_dobby]: As in, it's-too-fancy- that-it-will-be- messy-to-handle
[choroba]: bit vectors as keys?
[robby_dobby]: Hmm, I keep falling asleep at my desk, while maintaining an active appearance. Am I getting old?
