wanradt has asked for the wisdom of the Perl Monks concerning the following question:

Fellow devoted, not too many moons back i asked here about your knowledge and got some good hints to get my perl things be more unicode-aware, i mean node Pragma to handle unicode characters

Now I upgraded my perl to 5.10 and got a bit of surprise yelling me:

Too late for "-C63" option at ... line 1.
First i thougt it as bug, but from perldelta i read:
The -C option can no longer be used on the #! line. It wasn't working there anyway.

Maybe it wasn't working at all, but for me it somehow still worked. So, i'm looking for alternative: how can i turn UTF8 on on every possible IO from inside of code.

There is also option to use env-variable PERL_UNICODE, but this is not always option. For example, how can i turn the variable on running CGI-script?

TIA

Nġnda, WK

    -C63 is completely unreadable. Please use -CSDA instead. It's a bit better.

    You can do two of those letters using open: 

    use open IO     => ':encoding(UTF-8)';  # -CD
use open ':std' => ':encoding(UTF-8)';  # -CS

    But the simplest solution is not change anything and actually use the shebang line by launching the script directly, not as an argument to perl.

[d/l]

      Could you, please, be more specific about your last sentence? How to launch directly?

        Type script.pl, not perl script.pl
