How to decode an RFC 2047 encoded email header in Ruby?
问题 I have the following header: From: =?iso-8859-1?Q?Marta_Falc=E3o?= <marta.falcao@example.com.br> I can easily split out the stuff before the < , which leaves me with "=?iso-8859-1?Q?Marta_Falc=E3o?=" What can I use to turn this into "Marta Falcão" ? 回答1: Using the newer Mail gem: Mail::Encodings.value_decode(str) or Mail::Encodings.unquote_and_convert_to(str, to_encoding) 回答2: Thanks to Roland Illig for his comment, which led me to two options: install rfc2047-ruby and call Rfc2047.decode
