This is likely the result of a recent fix (?) as per #14952 after a too long struggle...

[msawyers]

The issue only exist on 2.3.1 can be replicated on vanilla instance

[msawyers]

Any assistance with this?

[gwharton]

If the emails are plain text then there is another bug where plain text emails are no longer sent as valid MIME emails so email clients may refuse to handle utf-8 encoding as that is only valid in MIME emails. See #22103.

[msawyers]

Yes, thats whats happening, issue still exist on Magento 2.3.2

[gwharton]

Yes. Plain text emails are currently broken in 2.2 and 2.3. Since 2.2.8 and never worked in 2.3.
