Expectation: when using cell contents as strings in a formula, the
strings should contain exactly the cell's text contents

Actual: the resulting string is wrapped in parentheses

I can find nothing in the documentation that suggests this is expected,
and it is quite unintuitive if you want to (for example) filter on
a column.

#+TITLE: text formula repro

| Key | Value        |
|-----+--------------|
| A   | [40, 65, 41] |
| B   | [40, 66, 41] |
#+TBLFM: $2="$1"

Here you can see that the contents of the Key column were wrapped in
parentheses (ASCII 40 and 41) when turned into strings.
