This issue was labelled with: A-libs in the Rust repository

Use case:

• reporting the position of the error to the user

Possible candidates:

• mark first_non_utf8_index() as public
• change from_utf8{_owned}'s return type from Option to Result<_, uint>

Since it's possible to recover from such an error, it would also be nice if these returned all encoding errors.
