Passing strings as arguments

[cc89]

I'm getting weird runtime behavior with the MySQL C++ connector. I've narrowed the problem down but have no idea what's happening.

header

#ifndef DATABASE_H__
#define DATABASE_H__
#include <string>
#include <cppconn/driver.h>
#include <cppconn/exception.h>
#include <cppconn/connection.h>
#include <cppconn/statement.h>
#include <cppconn/prepared_statement.h>

using namespace std;
using namespace sql;

class Database
{
	string url, schema, user, pass;
	struct Driver* driver;
	struct Connection* con;
	bool connect();

public:
	Database(string url, string schema, string user, string pass);

};

#endif 

source

#include "stdafx.h"
#include "Database.h"

using namespace std;
using namespace sql;

Database::Database(string url, string schema, string user, string pass)
	:url(url), schema(schema), user(user), pass(pass)
{
	if (connect())
	{
		con->setSchema(schema);
	}
}

bool Database::connect()
{
	try
	{
                cout << "TEST: " << url << endl;
		driver = get_driver_instance();
		con = driver->connect(url, user, pass);
		return true;
	}
	catch (SQLException &e)
	{
		cout << "Database::connect: " << e.what() << endl;
		return false;
	}
}

If I create a Database object in the main function and pass it a URL, username and password like so...

Database* db = new Database("tcp://localhost:3306", "root", "root");

This is what I get during runtime...

TEST: tcp://localhost:3306
Database::connect: Unknown MySQL server host '©yñ' (11004)
Press any key to continue . . .

As you can see, '©yñ' is not what I passed into the constructor. However if I modify the Database::connect() method...

bool Database::connect()
{
	try
	{
                cout << "TEST: " << url << endl;
		driver = get_driver_instance();
		con = driver->connect("tcp://localhost:3306", "root", "root"); //modified this line
		return true;
	}
	catch (SQLException &e)
	{
		cout << "Database::connect: " << e.what() << endl;
		return false;
	}
}

Everything seems to work fine. Does anyone know what's going on here? I'm using VC++ for this.

Update: I googled for a bit and found out that this issue might have had something to do with the character encoding. I got around it by passing each string's contents as an array of characters instead.

bool Database::connect()
{
	try
	{
                driver = get_driver_instance();
		con = driver->connect(url.data(), user.data(), pass.data()); //call data() function for each string
		return true;
	}
	catch (SQLException &e)
	{
		cout << "Database::connect: " << e.what() << endl;
		return false;
	}
}
