On Linux, with GTK2-Gnome2 gvim (Huge) and UTF-8 system locale, "vim file"
reads the Latin1 file, sets 'fenc' to Latin1 and displays it correctly. No
bug. ('fencs' is set to: ucs-bom,utf-8,default,latin1 .)
On the same platform, "view - <file" displays the file correctly, with 'fenc'
empty and 'enc' set to UTF-8. I don't know whether this is a bug (I think not).

You are at a business lunch when you are suddenly overcome with an
uncontrollable desire to pick your nose. Since this is definitely a
no-no, you:
(a) Pretend to wave to someone across the room and with one fluid
motion, bury your forefinger in your nostril right up to the 4th
joint.
(b) Get everyone drunk and organize a nose picking contest with a prize
to the one who makes his nose bleed first.
(c) Drop your napkin on the floor and when you bend over to pick it up,
blow your nose on your sock.
