Characters Not In String Function
Character Arrays Class

Public Function CharactersNotInString( _
    ByVal vValue As Variant _
    ) As Variant

Return a string containing the characters with ASCII values from 0 (zero) through 255 that do not appear in string vValue.

Examples: 
    CharactersNotInString("") = EveryCharacter
    CharactersNotInString("ABBCCC") = Chr$(0) + ... + "@" + "D" + ... + Chr$(255)
    CharactersNotInString("ABBCCC") = DifferenceCharacters(EveryCharacter, "ABBCCC") ' #3

    DifferenceCharacters Function
    EveryCharacter Property
Note: Similar to calling the DifferenceCharacters function with vStringOne set to EveryCharacter and vStringTwo set to vValue as in example #3.

vValue: The string containing the characters that are to be excluded from the result string. Function returns Null if vValue is Null or cannot be fixed up to a String.

Note: Function uses the ASCII value of characters to determine if they match, which is in effect the same as using Binary comparisons.

Note: The characters in the result string are always returned in order by their ASCII value.
