As stated in the specification,

  [Escape Characters] The escape character \ removes any special meaning that
  is associated with the non-null, non-newline character immediately following.
  This may be used to include whitespace (but not newlines), metacharacters,
  and single/double quotes in a TEXT token.  The escape character is removed.

Thus "x\ y" is equivalent to "x y", not "xy".
