Re: avoid writing 'use utf8' in every script

What you really want may be possible; however, what you describe is illegal syntax.

Consider this example script (see Note below):

#!/usr/bin/env perl

use utf8;

sub smiley {
    print "Smiley\n";
}

sub ☺ {
    print "Smiley\n";
}

Here's what happens when you run this:

$ pm_script_with_utf8.pl
Illegal declaration of anonymous subroutine at ./pm_script_with_utf8.p
+l line 9.

The documentation for the utf8 pragma even tells you this:

"One can have Unicode in identifier names, but not in package/class or subroutine names."

If you provide a short code example, that might serve to illustrate exactly what you're trying to achieve.

[Note: I've used <pre>, instead of <code>, tags for the code containing Unicode characters. This is to allow the actual characters, instead of character entity references, to be displayed. Please do the same with any such code you post.]

Q. In your UTF-8 Perl script, which characters in the subroutine name "`smiley`" aren't Unicode characters? A. None of them. In fact, every character in your Perl script is a Unicode character. ☺ (The Perl documentation is inaccurate. It uses the word "Unicode" incorrectly in the sentence you quoted.) Jim	[reply] [d/l]

Update: I replied to the wrong post. It should've been to Re^2: avoid writing 'use utf8' in every script, making this lame joke even lamer. If anyone with "movenodeability" wants to transplant this reply, it would be appreciated! tobyink: Odd, I always thought ☺ resembled the Kanji for Simiru, as in Simiru, Mirikuru gaaru! </end_of_lame_joke> ...roboticus Unicode: Making a job hard to do correctly (like i18n) nearly freakin' impossible.

I took Japanese lessons in primary school. That was a long time ago, and I've forgotten much of it. However, I'm pretty sure that "☺" is not a Japanese word. `use Moops; class Cow :rw { has name => (default => 'Ermintrude') }; say Cow->new->name`	[reply]

Lets say i have 2 scripts: main.pl code: #!perl use utf8; do 'main_include.pl'; sub über { return shift; } main_include.pl code: use utf8; über('hi'); So let's say i have a lot of files like main_include.pl and every is using über() function. I am trying to find a way tell perl that all inside scripts will use utf8-named functions and there is no need to indicate it every time i call them	[reply]
