I'm having some issues related to special characters in my transactional emails, it looks like a native bug in Magento 2.1.7 (It seems still in 2.2.3)

Steps to reproduce:

I've set the store name as "Bob's Burgers" in the admin panel, then I go to the store frontend and go to Request a password reset, in order to receive an email including the store's name that I did the setup in the admin panel.

Expected result:

The email's subject should be Reset your Bob's Burgers password as I did the setup in the admin panel.

Actual result:

The subject is Reset your Bob's Burgers password

How could I fix it?

Answer 1

Using this reference on the Magento 2 Repository in Github, you can create a plugin to fix like that:

di.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Email\Model\Template">
        <plugin name="mail_subject" type="VENDOR\MODULE\Plugin\Template" sortOrder="100" />
    </type>
</config>

Template.php

namespace VENDOR\MODULE\Plugin;

class Template
{
    public function afterGetSubject(
        \Magento\Email\Model\Template $subject,
        $result
    ) {
        return htmlspecialchars_decode((string)$result, ENT_QUOTES);
    }
}
