Perl supports unicode in its core, and that include identifier names
using exotic characters.

Erm, isn't this an effective "No"?

Perl is coming close to having full unicode support. '★' is not an
alphabetic or numeric character and has no place in an identifier. That
is why both Perl and Java reject it. Let's see what Perl can do:
#!/usr/bin/perl
use strict;
use warnings;
use utf8;
package 方;
our $str北="北方有佳人,絕世而獨立。\n一顧傾人城,再顧傾人国。"
. "\n寧不知倾城与倾国。\n佳人難再得。";
our $strβ = "θπαβγλϕρκψ ≤≥≠≈⊂⊃⊆⊇∈
ⅇⅈⅉ∞∆° ℵℜℂℝℚℙℤ ℓ∟∠∡ ∀∃ ∫∑∏
⊕⊗⊙⊚⊛∘∙ ★☆";
sub new {
my $class = shift;
my $self = {
str北 => \$str北,
'strβ' , \$strβ,
};
bless ($self, $class);
}
sub str北 {
${ (shift)->{str北} };
}
sub strβ {
${ (shift)->{strβ} };
};
package Test方;
sub do {
binmode STDOUT, 'utf8';
my $obj方 = 方->new();
$\ = "\n";
print $obj方->str北();
print '----------------';
print $obj方->strβ();
}
Test方->do();
