Public Function StringCharactersBitwiseAndNumber( _
      ByVal vString As Variant _
    , ByVal vNumber As Variant _
    ) As Variant

Perform the bitwise "And" operation on each of the characters within a string.
The operation is performed between the number and each character within the string.

Truth table: 
    AND     Var2
             0 1
           +-----
    Var1 0 | 0 0
         1 | 0 1
Examples: 
    StringCharactersBitwiseAndNumber(Chr$(193) + Chr$(194), 127) = Chr$(65) + Chr$(66) = "AB"
    StringCharactersBitwiseAndNumber("BC",  31) = Chr$(2) + Chr$(3)
    StringCharactersBitwiseAndNumber("BC", 128) = Chr$(0) + Chr$(0)
