Unicode character without glyphs in used fonts is normally shown as
something like U+FFFD REPLACEMENT CHARACTER (usually either a
rectangle or a white question mark in black rhomb, GTK apps have a
habit of representing this as a square with four hex digits inside).
This looks more like a unicode whitespace character, `\s` does not
match even rather common U+00A0 NO-BREAK SPACE (common enough to have
&listchars suboption that allows displaying it differently from
regular space), not to mention U+2000 EN QUAD .. U+200A HAIR SPACE or
other space characters above this range.

To check what your space actually is (and thus how you can match it
with something like `\%u00A0` (example will match U+00A0)) place
cursor on one of such spaces and type `ga`, this will show something
like

< > 160, Hex 00a0, Octal 240

, you need "Hex" value.
