Distortion of characters when viewing the original message

[alglyzin]

After updating to the latest version 2.1.4, the html version incorrectly displays text other than English characters.
The email arrives in the correct encoding, but is viewed as in the screenshot:

I am also interested in what causes it and how it can be fixed...

Has anyone taken a look at this? I'm also experiencing the same issue and the clients are not happy about it...

Same issue, this happens for incoming E-Mails as well, resulting in the webhooks breaking the encoding and passing the invalid characters.

Seems this line is responsible for handling the encoding, though I don't have a fix

postal/config/initializers/mail_extensions.rb

Lines 89 to 105 in 2f62baa

	def decode_body_as_text
	body_text = decode_body
	charset_tmp = begin
	Encoding.find(Ruby19.pick_encoding(charset))
	rescue StandardError
	"ASCII"
	end
	charset_tmp = "Windows-1252" if charset_tmp.to_s =~ /windows-?1258/i
	if charset_tmp == Encoding.find("UTF-7")
	body_text.force_encoding("UTF-8")
	decoded = body_text.gsub(/\+.*?-/m) { |n| Base64.decode64(n[1..-2] + "===").force_encoding("UTF-16BE").encode("UTF-8") }

	body_text.force_encoding(charset_tmp)
	decoded = body_text.encode("utf-8", invalid: :replace, undef: :replace)
	end
	decoded.valid_encoding? ? decoded : decoded.encode("utf-16le", invalid: :replace, undef: :replace).encode("utf-8")
	end
