UTF-8 Bad Encoding when Using ZF2 dbAdapter for mySQL for Update - mysql

Question

I am getting the Exception when I attempt to update the record with "tableGateway" object:
Zend\Db\Adapter\Exception\InvalidQueryException
Statement could not be executed
(HY000 - 1300 - Invalid utf8 character string: 'C`\xC3`\xB3`digo')
I have the following table structure with data in mySQL:
CREATE TABLE `clientes` (
`Código` int,
`Nome` varchar(50),
`Descricao` varchar(150)
....
);
INSERT INTO `clientes` (`Código`, `Nome`, `Descricao`)
VALUES (1, 'Test Nome', 'Test Descricao');
The database encoding is 'latin1', but the database configuration is as shown:
'mycnn' => array(
'driver' => 'pdo',
'dsn' => 'mysql:dbname={$mydb};host={$myhost}',
'username' => '{$myuser}',
'password' => '{$mypassword}',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
),
)
As you can see the above scenario, I have setup the driver for "UTF-8", the column name "Código" has a special character and renaming this column is not an option.
The syntax that I am using for updating in the model is:
$set = array("Nome" => "Edited Test");
$where = array("Código" => 1);
$this->tableGateway->update($set, $where);
After that, the ZF is parsing the SQL throwing the Exception:
UPDATE "clientes" SET "Nome" = 'Edited Test' WHERE "C`\xC3`\xB3`digo" = 1
I have also removed the UTF-8 option, since the catalog is "latin1_swedish_ci" without success.
I would appreciate anyone who gives me a hint how to face this issue.
Thanks in advance.

Make sure your database encoding type is UTF-8.
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
),
Make sure fields have utf8_general_ci.
In your layout phtml head has
<meta charset='utf-8'>
Updated
As you said you are not able to change encoding to utf-8 so use one of the following commands using driver_options
'SET NAMES \'latin1\'' or 'SET CHARACTER SET \'latin1\''
For more details check out the doc please!
When problem with column name which has latin1 characters
Just pass the condition as string not an array as the second argument into TableGateway's update() method. But you must set this 'SET NAMES \'UTF8\'' in your driver_options.
$id = 1;
$where = "Código = {$id}";
// Or use this way
$where = "Código = 1";
$this->tableGateway->update($set, $where);
