For some reason API response contain incorrect data

'x_address' => '*** Bois-de-Ch�ne',

'x_city' => 'Qu�bec',

Look like issue on authorize side.

Magento 2.1.7 with patch https://support.magento.com/hc/en-us/articles/360024368392-Update-Authorize-Net-Direct-Post-from-MD5...

for versions 2.0.X and 2.1.X

Hello @alex_zakatov 

Yes some characters are not accepted by authorize.net and hence it throws the error while placing an order.

You will need to clear that out programmatically before processing the order.
