Well, at least in 1.8.2 they can handle empty strings, but it is 
somewhat tricky:

irb(main):001:0> :"#{}"
ArgumentError: interning empty string
         from (irb):1
irb(main):002:0> :"#{""}"
=> :

Symbol#inspect doesn't quite work there, though. :)

Also, there was more cases like :"$10" that don't work in 1.8.2 and I'm 
not sure if they have already been fixed for 1.9. I think I listed most 
of them in [ruby-core:03573].
