"[\240]+" doesn't do what you want. Octal 240 is a unibyte character,
so that string constant specifies a unibyte string. When this unibyte
string is converted to multibyte, the raw byte becomes codepoint
#x3ffa0.
You should use either of these instead:
(font-lock-add-keywords nil '(("[\u00a0]+" (0 'foo t))) 'APPEND)
(font-lock-add-keywords nil '(("[ ]+" (0 'foo t))) 'APPEND)
