I am trying to send a email with Korean text in the Subject. It doesn't get encoded correctly, even thought it does in body:

Here's a minimal reproducible sample.

use_secret_file("my_gmailr.json")
mail_title <- "[test]  안녕"
test_email <- mime(
  To = "myemailgmail.com",
  From = "myemailgmail.com",
  Subject = mail_title,
  body = " 
contents. 한국어
  ")
send_message(test_email)
# In gmail
Subject: [test] 안녕      # somehow encoding/decoding get's messed up
Body: contents. 한국어  # renders it fine

Here's my sessionInfo

You could use RFC 1342 (thanks to https://ncona.com/2011/06/using-utf-8-characters-on-an-e-mail-subject/):

mime(..., Subject = paste0("=?utf-8?B?", base64enc::base64encode(charToRaw(enc2utf8("안녕"))), "?=")
