Description Vadim Zeitlin 2006-04-02 19:36:36 UTC 
I must be missing something but why in C locale do I get this

% echo '+' | iconv -t utf7  # ok so far
+-
% echo -n '+' | iconv -t utf7;echo # and it's the same thing without newline
+-
% echo '+-' | iconv -f utf7 # and it works in the other direction too, good
+
% echo -n '+-' | iconv -f utf7 # but why doesn't it work without newline?
iconv: incomplete character or shift sequence at end of buffer

"+-" sequence seems to be valid UTF-7 according to my reading of RFC 1642 and
I'd also expect UTF-7 transformation to be reversible.

Fix in the upstream CVS.
