Need Help??

in thread Seeking Perl docs about how UTF8 flag propagates

As has been said in this thread (and elsewhere): To reproduce, use 5.012; or newer, or more explicitly: use feature 'unicode_strings';

I have the habit to always specify a minimum version I run in my programs, including demos for PerlMonks. I admit that it didn't occur to me that without a version declaration (or with a declaration of 5.010 or older) Perl behaves differently.

edit

I'm wondering why it got such a confusing name

from the docs

The 'unicode_strings' feature
use feature 'unicode_strings' tells the compiler to use Unicode rules in all string operations executed within its scope

calling it "unicode_rules" would make more sense to me.
