Converting strings to unicode

I have to turn strings into Unicode. I thought the best way to do this would be as followed

HTML Code:

---

For...Next to get the string
For...Next to take each character out of the string
For...Next to display each character in Unicode

---

The only problem I have is with the separation on each character in the string. I know I have to use a For...Next loop to check each spot in the string. But how would I move on past the first character?

Something like this, though I am not sure that the encoding is the one you want.

Code:

---

        Dim st As String = "Test"

        Dim myEnc As New System.Text.UnicodeEncoding

        Dim b() As Byte = New Byte() {}

        b = myEnc.GetBytes(st)

---

I get the basic idea, the encoding one you used isn't what I was looking for but I think I can turn it into what I need.
