Hm, one way to disable it (only in Vim, of course) would be
:map! <Char-0xA0> <Space>
which would replace any no-break space typed in Insert/Replace or
Command-line modes by a plain space. If you _do_ want to intentionally
enter no-break spaces sometimes, you'll need an additional mapping for
it, for example
:noremap! <S-F12> <Char-0xA0>
With these two mappings, either Space or Option-Space (or whatever
normally produces a no-break space) is just plain space, and Shift-F12
(safely out of the way, and something that you probably won't hit by
mistake) is no-break space.
Best regards,
Tony.
