That's the expected behavior when passing ' '. According to the docs:

If pattern is a single space, str is split on whitespace, with leading and trailing whitespace and runs of contiguous whitespace characters ignored.

With "whitespace" being space (" ") and \t, \n, \v, \f, \r.

"foo bar\nbaz \f qux".split(' ')
#=> ["foo", "bar", "baz", "qux"]

To split on space (U+0020) only, you have to use a regexp:

"foo bar\nbaz \f qux".split(/ /)
#=> ["foo", "bar\nbaz", "\f", "qux"]
