encoding - How to decode an RFC 2047 encoded email header in Ruby?

Question

posted Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

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 Falc?o"?

Using the newer Mail gem:

Mail::Encodings.value_decode(str) or Mail::Encodings.unquote_and_convert_to(str, to_encoding)
