Set title and description by code in one specific language

Hi,
I have a woocommerce and need change the translations in one languange programmatically. I have an csv file with the id (SKU) and the new translated title and description. How can i modify this in one specific language?
My title are like this “[:se]Title se[:en]Title en[:]
If use this:

$my_post = array(
      'ID'           => 99,
      'post_title'   => 'New title.',
      'post_content' => 'New content.',
);
// Update the post into the database
wp_update_post( $my_post );

My title become in “New title”.
And should be like this “[:se]New title[:en]Title en[:]”

Thanks!!
