It contains this string: "структура".
I am lost, can't find how to do it.
I guess, I have to use pack or regex, but I don't know where to start. I don't even know, what this encoding is called, although, I saw it before many times.
UPDATED:
I've figured it out. I realized that those 3 digit sequences are not decimal, but octal, so I've tried:
my $string = "\321\201\321\202\321\200\321\203\320\272\321\202\321\203
+\321\200\320\260";
$string =~ s/\\([[:digit:]]{3})/sprintf "%c", oct($1)/ge;
print $string;
And it Worked! :)
