find() doesn't find '|' for some reason

Here's some sample output and my code follows it. Why can't find() find '|'. It just dosn't make a bit of sense at all.

Code:

AL01463|Pell City|Saint Clair|B|02115|AL|35125|630|Birmingham (Ann and  Tusc)|13890|40|Charter Communications|Fairfield|Charter Communications|2

I'm calling StringExplode. That's the couts I posted above.

Code:

#include </usr/include/mysql++/mysql++.h>
#include <stdio.h>
#include <iostream>
#include <fstream>
#include <sstream>
#include <string>
#include <vector>

using namespace std;

void StringExplode(string str, string separator, vector<string>* results){
    std::cout << str << endl;
    int found;
    found = str.find(separator);
    while(found != string::npos){
        if(found > 0){
            results->push_back(str.substr(0,found));
        }
        str = str.substr(found+1);
        found = str.find_first_of(separator);
    }
    if(str.length() > 0){
        results->push_back(str);
    }
    std::cout << found << endl;
}

file::find::rule::procedural

File::Find::Rule::Procedural(3) 			User Contributed Perl Documentation			   File::Find::Rule::Procedural(3)

NAME

       File::Find::Rule::Procedural - File::Find::Rule's procedural interface

SYNOPSIS

	 use File::Find::Rule;

	 # find all .pm files, procedurally
	 my @files = find(file => name => '*.pm', in => @INC);

DESCRIPTION

       In addition to the regular object-oriented interface, File::Find::Rule provides two subroutines for you to use.

       "find( @clauses )"
       "rule( @clauses )"
	   "find" and "rule" can be used to invoke any methods available to the OO version.  "rule" is a synonym for "find"

       Passing more than one value to a clause is done with an anonymous array:

	my $finder = find( name => [ '*.mp3', '*.ogg' ] );

       "find" and "rule" both return a File::Find::Rule instance, unless one of the arguments is "in", in which case it returns a list of things
       that match the rule.

	my @files = find( name => [ '*.mp3', '*.ogg' ], in => $ENV{HOME} );

       Please note that "in" will be the last clause evaluated, and so this code will search for mp3s regardless of size.

	my @files = find( name => '*.mp3', in => $ENV{HOME}, size => '<2k' );
							   ^
							   |
		      Clause processing stopped here ------/

       It is also possible to invert a single rule by prefixing it with "!"  like so:

	# large files that aren't videos
	my @files = find( file	  =>
			  '!name' => [ '*.avi', '*.mov' ],
			  size	  => '>20M',
			  in	  => $ENV{HOME} );
