Yes, and here’s what I get when printing to PDF:

What’s the problem? Emails and PDFs may *contain* plaintext, but they aren’t 
raw plaintext, and never have been. The fact that one particular encoding of 
emails happens to look very similar to plaintext IFF you are using a language 
that only requires US-ASCII characters is a historical curiosity. Email 
encodings are completely transparent to the end user if you use an actual email 
program and not a text editor.

My honest and heartfelt advice is to please stop worrying about it, it’s been a 
solved problem for several decades now. If you have limited disk space, base64 
compresses really efficiently. Please don’t read your emails in vim, you’ll 
only generate excess cortisol and shorten your lifespan.
