Question: What was causing the confusion and incompatibility of the code points?
Answer: From early in its development, ASCII was intended to be just one of several national variants of an international character code standard, ultimately published as ISO/IEC 646 (1972), which would share most characters in common but assign other locally useful characters to several code points reserved for "national use."
