    The internal helper function CharacterRange takes two CharSet parameters A and B and performs the
    following:
    2. Let a be the one character in CharSet A.
    3. Let b be the one character in CharSet B.
    4. Let i be the character value of character a.
    5. Let j be the character value of character b.
    6. If i > j, throw a SyntaxError exception.
