encoding bug #5
Description
Hi,
I'm using the rfc2047 gem to parse mail headers read from an IMAP server. In rare cases the gem aborts with
Error incompatible character encodings: UTF-8 and ASCII-8BIT
Encoding::CompatibilityError
/var/lib/gems/2.1.0/gems/rfc2047-0.3/lib/rfc2047.rb:25:in gsub' /var/lib/gems/2.1.0/gems/rfc2047-0.3/lib/rfc2047.rb:25:indecode'
A parameter given to the rfc2047 decoder in this case was
"=?UTF-8?B?VW50ZXJzdMO8dHp1bmc=?=" <unterstützung@mx2.websitesbyrich.com>
which seems to be syntactically incorrect, since ü should have been rfc2047 encoded as well, but a decoder library should be able to deal with incorrect syntax, since this happens quite often, and not run into an encoding error.
regards
Hadmut
