Critical error during email loading

Hi,

I’m trying to insert articles in arabic, I’m doing a python automation to email the content and I’m getting critical error. I have encoded my email to utf-16, however I’m failing to get the encoding right for the images, is this the issue?

Note that the images are inserted into wordpress with the naming wrong, and when they failed to insert, the article was inserted successfully. I can provide you with more info as needed.

Here is an image example:

MIME-Version: 1.0
