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
