I am sending a custom email, the custom template data is in Spanish. if the template is in the English language it's working perfectly. but in Spanish language, it shows me unknown error. it's not working if characters are like: ú, ó

Its not working with below code:

{{trans "%body" body="Transacción"|raw}}


Unable to send mail: Unknown error

  • Is strange, we use the same format for an accented string: {{trans "Política de Privacidad"|raw}} Is your store locale set to spanish?

We can use HTML Codes for Spanish Language Characters ú to make it take ú in email template,

Make sure the type is html type="html" in YourVendor/YourModule/etc/email_templates.xml

Here are the different Spanish characters you may want to use:

Display FriendlyCode    NumericalCode   Hex Codes       Description

Á       Á        Á          Á          Capital A-acute
á       á        á          á          Lowercase a-acute
É       É        É          É          Capital E-acute
é       é        é          é          Lowercase e-acute
Í       Í        Í          Í          Capital I-acute
í       í        í          í          Lowercase i-acute

«       «         «          «          Left angle quotes

¡       ¡         ¡          ¡          Inverted exclamation point
€       €          €          €          Euro
₧                       ₧         ₧        Peseta

If still not working you can create plugin:

Define plugin: YourVendor/YourModule/etc/frontend/di.xml

<?xml version="1.0"?>
<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="YourVendor\YourModule\Plugin\Template" sortOrder="100" />

Create Plugin:

namespace YourVendor\YourModule\Plugin;

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