The UTF-encoded subject line can be split in the middle of a
multi-byte UTF-8 character which breaks RFC 2047.
Example :
Subject:
=?utf-8?b?zpHOnc6RzprOn86Zzp3Oqc6jzpcgzpPOmc6RIM6VzprOpM6lzqDOqc6jzpcgzpTO?=
=?utf-8?b?mc6UzpHOms6kzpnOms6pzp0gzqPOl86czpXOmc6pzqPOlc6pzp0gzpPOmc6RIM6V?=
=?utf-8?b?zpHOoc6Zzp3OnyDOlc6ezpHOnM6Xzp3Onw==?= 2018-19
which with strict decoding ( http://dogmamix.com/MimeHeadersDecoder/ ) gives :
Subject: ?????????? ??? ???????? ??????????? ?????????? ??? ??????
??????? 2018-19
