::*re:∑ (1+xⁿ)xⁱ - true.. if n and the bounds of the ∑ are known, then it could be a polynomial. But again, let us avoid symbolic manipulation. A simple array of real coefficients is what is required.

:::The use of negative exponents introduces several difficulties. One of which is that the notation allows for continued fractions (2x^3/4x^5/6x^7). Another difficulties is the treatment of discontinuities. Another one is that we do not know what precedence rules to use (1/2*3). And if we are not dealing with polynomials then that introduces other complexities (one of which is "what is the scope of this task? (x^x, 4^½, ...)" ). Also, you have left the treatment of parenthesis ambiguous and your "unicode characters which must be supported" list did not include the digits 0 -- even though it's a unicode character. --[[User:Rdm|Rdm]]
: I find this task objectionable, if for no other reason than promoting bad typography. The unicode super-/subscripts are only good for when you don't have a way to mark up text. They are generally too small, inflexible, and unpleasant to look at. And, I don't see any practical merit in parsing such strings: I don't see why a human would carefully type out those difficult symbols as input data to a program, and if it's generated by machines, you might as well tell the machine to do a better job by writing structured/properly marked up data. --[[User:Ledrug|Ledrug]] 03:00, 19 November 2011 (UTC)
