Translations do not work when run via cron

[fooman]

Preconditions

1. Magento 2.1.3 (and earlier)

Steps to reproduce

1. Install a language pack, for example composer require imaginaerum/magento2-language-fr-fr
2. Create a new Store View "French"
3. Select fr_FR locale for this Store View
4. Change Stores > Configuration > Sales > Sales Email > General Settings > Asynchronous sending to Enabled
5. Place a new order from the French store
6. Ensure Magento's cronjob bin/magento cron:run is executing and that the order confirmation email has been sent

Expected result

1. Order Confirmation Email is sent in French

Actual result

Please note that the locale for email is correctly emulated as can be seen by formatting of the currency amounts.

Did you deploy the french language pack?

php bin/magento setup:static-content:deploy en_US fr_FR
php bin/magento indexer:reindex
php bin/magento cache:clean
php bin/magento cache:flush

Yes the email was correctly translated if sending asynchronously is disabled.

I have the same problem. Temporarily resolved with the following solution:
#3805 (comment)

    /**
     * @var \Magento\Framework\App\AreaList
     */
    private $areaList;

    public function __construct(\Magento\Framework\App\AreaList $areaList) {
            $this->areaList = $areaList;
    }

    private function execute() {
            $areaObject = $this->areaList->getArea(\Magento\Framework\App\Area::AREA_ADMINHTML);
            $areaObject->load(\Magento\Framework\App\Area::PART_TRANSLATE);

            var_dump(__('Registered'));
    }

@reindert-vetter thanks for confirming. I have suggested a fix in this PR #8413 which is the same solution just on a higher level (cron not only the template). If you could confirm that my changes here https://github.com/magento/magento2/pull/8413/files also work for you that be great.

Hallo, I have "solve" this issue with using \Magento\Store\Model\App\Emulation::startEnvironmentEmulation() function before sending and stopping after.
