Compare:

#! /usr/bin/perl
use warnings;
use strict;
use feature qw{ say };
use utf8;
 
my @strings = ('школы',
               "\xd1\x88\xd0\xba\xd0\xbe\xd0\xbb\xd1\x8b");
 
say for @strings;
 
binmode STDOUT, ':encoding(UTF-8)';
say for @strings;

The first two lines are the same:

школы
школы

but once the output knows it expects UTF-8 (the third and fourth line), the output is different:

школы
ÑколÑ

You probably didn't tell Sybase your strings are UTF-8.
