Plinking at unicode support in perl 5.8.0, I've succeeded in naming a sub Σ - "\N{GREEK CAPITOL LETTER SIGMA}", or Σ. The byte sequence for that is 0xD3 0x8E.
This may be tough to paste accurately, but it's a chance to see how it gets encoded and rendered, too.
#!/usr/bin/perl
# I hight sigma.pl
use 5.8.0;
use warnings;
use strict;
use utf8;
sub Ó~N {
my $sum = 0;
$sum += $_ for @_;
$sum;
}
print Ó~N 1..5;
print $/;
As I feared, I haven't found a way to paste utf8 into moz without 'helpful' interventions. The above is as rendered by vim, mangled by X. Anybody know how to do this?
Properly displayed, the sub and call read:
sub Σ {
...
}
print Σ 1..5;
Here's a one-liner to patch the listing (assuming ISO-8859-1):
perl -pi.bak -e's/Ó~N/\xD3\x8E/' sigma.pl
It's not easy yet for me to get my tools to cooperate.
After Compline,
