$functions: failed to find end of command substitution

$functions: failed to find end of command substitution

[Daniel Shahaf]

$ zsh -f
% f() {                             
  : $(:)
  "↓"
}
% : $functions
zsh: failed to find end of command substitution
% 

It doesn't happen if I change "↓" (U+2193) to "→" (U+2192).
