=head2 jcu2qwe ( $string, [ $encoding ])

This method converts $string from Jcuken to Qwerty.

Optional $encoding parameter allows to specify $string's encoding (default is 'windows-1251')

=cut

sub jcu2qwe {
  my $val = shift;
  my $enc = shift;
  Encode::from_to($val, $enc, 'windows-1251') if $enc;
  my $res = '';
  foreach (split //, $val) {
    $_ = $jcu2qwe{$_} if $jcu2qwe{$_};
    $res .= $_;
  }
  return $res;
}

=head2 qwe2jcu ( $string, [ $encoding ])

This method converts $string from Qwerty to Jcuken.

Optional $encoding parameter allows to specify result encoding (default is 'windows-1251').
It is also used as $string encoding if you have cyrillic in it.

=cut

sub qwe2jcu {
  my $val = shift;
  my $enc = shift;
  Encode::from_to($val, $enc, 'windows-1251') if $enc;
  $enc = 'windows-1251' unless $enc;
  my $res = '';
  foreach (split //, $val) {
    $_ = $qwe2jcu{$_} if $qwe2jcu{$_};
    Encode::from_to($_, 'windows-1251', $enc);
    $res .= $_;
  }
  return $res;
}
