I thought I'd put my two cents in ...

#!/usr/bin/perl -wl
use strict;

for my $f( ['the','there'],
           ['abcde','gcdabef'],
           ['abe','lbbe'],
           ['forky','fork'] )
{
    print "@$f =>", fooey($f);


}

sub fooey {
my ($this,$that) = @{$_[0]};

  my $yes;
  for my $char(split'',$this)
  {
    ++$yes if $that =~ /\Q$char\E/;
  }

  return $yes == length $this? 1: 0;
}


__END__
the there =>1
abcde gcdabef =>1
abe lbbe =>0
forky fork =>0

my second take on this...

#!/usr/bin/perl -wl
use strict;

for my $f( ['the','there'],
           ['abcde','gcdabef'],
           ['abe','lbbe'],
           ['forky','fork'] )
{
    print "@$f =>", fooey($f);


}

sub fooey {
  my ($this,$that) = @{$_[0]};

  my %yes;
  my $char = quotemeta $this;
  {
    $that =~ s/([$char])/$yes{$1}++/ge;
  }

  return ((scalar(keys %yes) == length $this? 1: 0);
}


__END__
the there =>1
abcde gcdabef =>1
abe lbbe =>0
forky fork =>0
