summary (to those who does not read source-changes):
- finger does not let 8bit characters through. it convers anything
with 2^7 bit set into M-x on sending (fingerd), and strips off
2^7 bit on receiving (finger)
- kim is trying to make finger 8bit thru. kim changed sender/receiver
side check to isprint(), which is locale dependent. kim says LANG
(or LC_CTYPE) setting should be sufficient to change behavior.
- itojun is arguing that: (1) protocol-wise it has to be ASCII by
default, from RFC (2) we need an explicit agreement between sender
and receiver to use non-ASCII charset, so there has to be a
protocol extension (define "charset" directive and submit i-d),
(3) the change has to be backed out until #2 is accomplished,
(4) isprint() change does not consider multibyte case at all.

as far as I checked FreeBSD and OpenBSD has the same behavior
as NetBSD (of yesterday) - escape any non-ASCII chars with M-x on
sending, and strip off 2^7 bit on receiving.
