Here’s what I would do (which is probably not the nicest way of doing it). Just
enable \obeyspaces while reading the argument to \EmptyLetters, then disable
it again immediately (that is needed if you have to go back to TeX from Lua):

\def\EmptyLetters
 {\obeyspaces\doEmptyLetters}

\def\doEmptyLetters#1%
  {\normalspaces
   ...
  }

and in \whatever you then need \doifinstringelse{ }{#1}

Best wishes,
Taco
