Yeah, oddly, there's no straightforward way to get an unaltered file
into a shell variable.  Even
  read -rd '' < file
trims off trailing newlines.  The only somewhat-obvious way is to use
  zmodload zsh/mapfile
  var=$mapfile[file]
but up until a recent dev version, on platforms that don't implement
memmap that just sneakily reverts to $(<file).

I'm expecting Roman or someone to point out a different trick I've forgotten.
