From the article: "Overall, Unicode is yet another encoding scheme."
It is more than that - for instance, it includes algorithms as well... for instance, dealing with RTL languages with ordering and shaping rules (i.e. Arabic), how to know what to do when RTL languages are mixed with LTR (is that '.' at the end of '123' a decimal point, or a period? (determines if it goes to the right or the left or the sequence)) and how to know when data is equivalent despite being normalized or not, etc...
