The thing about outputting super/subscript in term is that it will vary from system to system. Experiment with the '\x##' replacing ## with any hex number from 01 to FF. Eventually you will find the characters you want to use.
this will print a list of every character for you:
nums = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f']
for a in nums:
for b in nums:
exec("print '\\\\x"+a+b+": \\x"+a+b+"'")
