Re: Substr cannot extract last special character

Hi, It shows Ù, when used -2 offset, due of two byte length of unicode chars.

#!/usr/bin/perl
my $ohm = qw(24Ù);
$unit = substr $ohm,-2;
print "$unit","\n";

In particular, if you embed utf8 chars in the program source, you have to let perl know with the utf8 pragma: `my $x ='Ù'; print length($x), "\n"; # prints 2` [download] compared with `use utf8; my $x ='Ù'; print length($x), "\n"; #' prints 1` [download] Dave.	[reply] [d/l] [select]
