IIUC, the reason is that when invoking the shell, gvim gives that shell
a "dumb" terminal, which emulates a teletypewriter: it can move the
"paper" forward but not backward, it cannot "clear the screen", and it
cannot "go to" an arbitrary line & column; I'm not sure whether it has
colour and/or bold/underline/italic capabilities. Now the "man" program
expects its $MANPAGER to be the "less" program, or a reasonable
substitute for it, and "less" expects a video terminal working like a
"text-mode TV", not like a teletypewriter.
The weird characters are ANSI sequences used to set or clear boldface
and underline display modes: IIUC most video terminals can be set to
accept them, sometimes with the help of some "device driver" such as
(for MS-DOS) ANSI.SYS used to be.
IMHO, when using gvim, you had better run "man" in a separate xterm or
similar window (though it would not allow getting the manpage for the
word under the cursor, except via an additional paste operation), or
else, use Console Vim rather than gvim if you expect to be able to get
that functionality.
I think there are settings (but I don't know what) to tell man to avoid
bold & underline, and you might try setting $MANPAGER to more when
running "man" from gvim, but the latter would mean reading the man page
from begin to end, never going back.
Best regards,
Tony.
