Re: UTF-8: Trying to make sense of form input

in reply to UTF-8: Trying to make sense of form input

When you intend to send utf8 character data back to the client browser from a cgi script, you really should do this at the very start:
binmode STDOUT, ":utf8";
and make sure that strings coming from the script itself, or from server-side resources (files, database or whatever) are likewise properly flagged as (known to be) utf8 strings.

When you are getting utf8 characters in form data from the client browser, you have to use the Encode module -- decode('utf8',$cgi->param('foo')) -- as indicated in the replies above, so that the parameter value will be treated correctly by perl as a utf8 string.

[Corion]: marioroy: Oh, that's always cool, having API-compatible modules. This makes testing and comparing things much easier
[marioroy]: IPC in MCE::Shared can handle 400k (sends) per second. That's seems a lot for being a pure-Perl module. After making the release, will come back and post a solution for a node by a fellow wanting faster logging.
[Corion]: While working on WWW::Mechanize:: Chrome, I had the suspicion that AnyEvent was doing something wrong, but I was able to swap it out for Mojolicious and the error persisted.
[Corion]: Of course, the error was in my own code ;)
[marioroy]: Corion, start and start_child in MCE::Hobo::Manager return a MCE::Hobo object, whereas P::FM returns the PID. I can have it return the PID though. I tried Hobo::Manager with several P::FM modules, just changed P::FM to MCE::Hobo::Manager and it works.
[marioroy]: I also have a Hobo driver for Forklift allowing folks to use in multiple classes, no conflicts with one another. That's not possible for P::FM.
[Discipulus]: congrats marioroy!
[marioroy]: CORE::wait works well eventhough multiple instances or classes using Hobo::Manager.
[Corion]: marioroy: I'm not sure what the normal use for the PID is in P:FM, but I guess that most programs just ignore or log it
