SQLSTATE[22021]: Character not in repertoire - database

Question

I'm having this problem while seeding my PGSQL Database:
Illuminate\Database\QueryException : SQLSTATE[22021]: Character not in repertoire: 7 ERROR: secuencia de bytes no válida para codificación «UTF8»: 0xe3 0x83 0xe2 (SQL: insert into "races" ("name", "public_name", "members", "updated_at", "created_at") values (harp��a, Harpía, 23, 2018-04-21 20:30:20, 2018-04-21 20:30:20) returning "id")
at C:\Sandbox\rpgforum\vendor\laravel\framework\src\Illuminate\Database\Connection.php:664
660| // If an exception occurs when attempting to run a query, we'll format the error
661| // message to include the bindings with SQL, which will make this exception a
662| // lot more helpful to the developer instead of just the database's errors.
663| catch (Exception $e) {
> 664| throw new QueryException(
665| $query, $this->prepareBindings($bindings), $e
666| );
667| }
668|
Exception trace:
1 PDOException::("SQLSTATE[22021]: Character not in repertoire: 7 ERROR: secuencia de bytes no válida para codificación «UTF8»: 0xe3 0x83 0xe2")

Please use the argument -v to see more details.
And this is my Seeder's code:
<?php
use Illuminate\Database\Seeder;
use App\Models\Race;
class RaceTableSeeder extends Seeder
{
/**
* Run the database seeds.
*
* #return void
*/
public function run()
{
$races = [
'Humano',
'Orco',
'Elfo',
'Harpía',
'Enano',
];
for ($i = 0; $i < count($races); $i++) {
$race_i = utf8_encode($races[$i]);
$race = Race::create([
'name' => strtolower($race_i),
'public_name' => $race_i,
'members' => mt_rand(10,30),
]);
} // for
}
}
My database configuration:
pgsql database
My config.database file config:
config.database file
Is there any solution for this problem? I can find the way to get rid of this problem...
EDIT:
I just noticed something weird. I got two records in my database:
database records
And both of them have symbols that gave me problem with the seeder. Maybe the problem is within the seeders logic? I'm doing the exact same thing I do the whole time with my Laravel/Postgresql projects so i can't find the reason why i can't seed words with accent mark but i can use a simple form to store that kind of information. Any ideas ?
