[julia-users] readdir returns inconsistent types

[samuel_ainsworth]

 Why does readdir return a Union of two different string types instead of a 
consistent one?

julia> typeof(readdir("."))
Array{Union(UTF8String,ASCIIString),1}

I was expecting Array{UTF8String,1} or Array{ASCIIString,1}. It's not a 
serious issue but still quite unexpected.
