[jira] [Created] (ARROW-11693) [C++] Add string length kernel

Neal Richardson created ARROW-11693:
---------------------------------------

             Summary: [C++] Add string length kernel
                 Key: ARROW-11693
                 URL: https://issues.apache.org/jira/browse/ARROW-11693
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Neal Richardson
             Fix For: 4.0.0


We have "binary_length" but that doesn't handle UTF-8 the way we need for this. Example (from R):

{code}
> string <- "áéíóú"
> nchar(string)
[1] 5
> arrow:::call_function("binary_length", Scalar$create(string))
Scalar
10
{code}
