[jira] [Created] (ARROW-11434) Length kernel returns bytes not character length

Mike Seddon created ARROW-11434:
-----------------------------------

             Summary: Length kernel returns bytes not character length
                 Key: ARROW-11434
                 URL: https://issues.apache.org/jira/browse/ARROW-11434
             Project: Apache Arrow
          Issue Type: Bug
          Components: Rust, Rust - DataFusion
            Reporter: Mike Seddon
            Assignee: Mike Seddon


The rust `length` kernel currently counts number of bytes/octets rather than characters given that Arrow uses UTF8 encoding.

This means that the result of the `length` kernel on a string like `josé` will be 5 bytes rather than 4 characters.
