Align the text in emails from right to left.

Hello everyone
How do I align the text in emails from right to left. (I mean order status messages) The entire site works right to left alignment but the messages are still left to right.
Thank you all

Try setting this line
https://github.com/litecart/litecart/blob/38b2f6e4e992a82ff6a8bf423cf6adc5011588a0/public_html/includes/templates/default.catalog/pages/printable_order_copy.inc.php#L47

To
<section class="page" data-size="A4" dir="rtl">

Oh wait you meant order status update notifications?

That is cooked here:
https://github.com/litecart/litecart/blob/38b2f6e4e992a82ff6a8bf423cf6adc5011588a0/public_html/includes/entities/ent_order.inc.php#L749-L802

Try changing this:
$message = strtr($order_status->email_message, $aliases);

Into this:
$message = '<div dir="rtl">'. strtr($order_status->email_message, $aliases) .'</div>';

Very cool...
 All messages have the alignment modified. Except for the order confirmation message, the alignment has not changed.
When making a purchase, the customer receives a message with the order details. This message has not modified the alignment.

What comes to the email body for the order confirmation it is plain text. So there is no parameter we can send. I read plain text should have the Right to left byter mark. https://en.wikipedia.org/wiki/Right-to-left_mark

Try changing:

$message = strtr(language::translate('email_order_confirmation', $message, $language_code), $aliases);

To: 

$message = "\u200F" . strtr(language::translate('email_order_confirmation', $message, $language_code), $aliases);

or

$message = "\xe2\x80\x8f" . strtr(language::translate('email_order_confirmation', $message, $language_code), $aliases);

All my attempts failed.

Thank you, dear Tim.

Thank you for the kind words.
Let's not give up just yet.

Can you translate this for me and I will be able to make some tests.

The translation is done

I did numerous tests with the right to left byte mark and nothing seems to work with plain text in Gmail. Makes me wonder how gmail users do it?

I wish I had a little experience in this area to help. But if this becomes possible for you later, make it part of the development of the script.
Thank you for your effort and interest.

Absolutely :)
