It is not an integer in this case. It's a string of characters and Split()
doesn't interpret it as an integer. Consequently it has nothing to do with
IgnoreVoid in my book.

If anything is wrong, it is your use of the separator. According to the
documentation (and the implementation!), the Separator argument is a *list*
of separator characters, i.e. "##" will not split against the string "##",
but it will split against "#" or "#".

To give a different example, if you had given the string "abc#123,456" and
separators "#," you would have gotten the array ["abc", "123", "456"].

I don't know what's the problem with your installation but on mine I get:

  $ gbx3 -e 'Split("hello##12345", "##").Join("|")'
  hello||12345

i.e. it works. Notice the empty string between "hello" and "12345"
in the context of what I explained about the separators above!
