Visit http://czyborra.com/utf/#UTF-7 for more info.

All of the above UTFs produce 8bit bytes that are not in ASCII and that
will get stripped on any terminal that is still set to character size 7
or any mail gateway that ensures RFC 822's rule that mail messages have
to be in ASCII. To solve that problem, David Goldsmith and Mark Davis
invented a mail-safe transformation format UTF-7. It was first published
in <a href="ftp://ftp.isi.edu/in-notes/rfc1642.txt">RFC 1642</a> in 1994,
prominently included as Appendix A.1 in The Unicode Standard, Version 2.0,
and now updated in <a href="ftp://ftp.isi.edu/in-notes/rfc2152.txt">RFC
2152</a>.
Mutt already supports utf-8. Supporting utf-7 would not hurt (or would
it?)
