If you have a human controlling the interpretation, UTF-7 was a good way of avoiding data being mangled by interfaces that insisted that unlabelled (indeed, sometimes, unlabellable) 8-bit text was UTF-8 or conversely, Latin-1 or code page 1252. The old Yahoo groups web interface for senders was pretty much restricted to 8-bit ISO-2022 encodings without it. C1 characters would be converted to Latin-1 on the assumption that they were Windows 1252. Browsers dropping UTF-7 support was a major inconvenience. Richard.
