I'd be interested to know about 'smaller' cases. Surely there
are 'larger' ones (like windows-1250, koi8, euc-*, etc), which
have printable characters in 128-160 range, but I'm not aware
of character set with control characters in range 161-255.

128-160 are control characters in iso-8859-*, so they are not safe
to pass without character set protocol extension.

Yes. Default of passing 33-127, 161-255 (in both finger and fingerd)
is as defensive, interop-friendly and convenient as we can get.
