title: Why does the unicode Superscripts and Subscripts block not contain simple sequences of all letters?
body: <p>The arrangement of the characters that can be used as super-/subscript letters seems completely chaotic. Most of them are obviously <em>not</em> meant to be used as sup/subscr. letters, but even those which are do not hint a very reasonable ordering. In Unicode 6.0 there is now at last an alphabetically-ordered subset of the subscript letters h-t in U+2095 through U+209C, but this was obviously rather squeezed into the remaining space in the block and encompasses less than 1/3 of all letters.</p>
  
  <p>Why did the consortium not just allocate enough space for at least one sup and one subscript alphabet in lower case?</p>
