I want to add an invisible character to a text string.

Dim myString As String
myString = "United States"

The following codes are not okey because the following codes seperate the string two parts.

I want to keep the string one part.

myString = "United" & " " & "States"
myString = "United" & Space(1) & "States"
myString = "United" & Chr(32) & "States"
myString = "United" & Chr(160) & "States"

There must be a character between United and States but that character must be invisible.

What character I should put to the following string instead question mark?

 myString = "United?States"
