RFC 2152 specifies that "+-" encodes a plus sign. The decoder saw no Base64 character after the `+', then swallowed the `-' as the optional end of a shifted sequence, so every literal plus sign was silently lost: $ echo '1 +- 1 = 2' | recode utf-7..utf-8 1 1 = 2 Output the plus sign. Also encode a plus sign as "+-", as recommended by RFC 2152, rather than as the longer, still valid, "+ACs-". Add a test.
