The function "string" of Calc does not support characters above 127,
see towards the end of
(info "(calc) Strings")
or
http://www.gnu.org/software/emacs/manual/html_node/calc/Strings.html

If I understand your example you can use just

| item | value |
|------+-------|
| a    |     1 |
| b    |     2 |
|------+-------|
| ∑    |     3 |
#+TBLFM: @>$2 = vsum(@I..@>>)

or

| item | value |
|------+-------|
| a    |     1 |
| b    |     2 |
|------+-------|
|      | ∑ = 3 |
#+TBLFM: @>$2 = vsum(@I..@>>); ∑ = %d
