Enumerate the error status values that are returned (possibly through an out parameter) from some methods in this utility. Note that some of the functions in this struct have a return value that is non-negative on success, and one of these values when an error occurs, so all of these values must be negative to distinguish them from a "success" value.

enum ErrorStatus;| Name | Description |
|---|---|
k_END_OF_INPUT_TRUNCATION | End of input was reached partway through a multibyte UTF-8 sequence. |
k_UNEXPECTED_CONTINUATION_OCTET | End of input was reached partway through a multibyte UTF-8 sequence. |
k_NON_CONTINUATION_OCTET | A non-continuation byte was expected but not found. |
k_OVERLONG_ENCODING | The encoded Unicode value could have been encoded in fewer bytes. |
k_INVALID_INITIAL_OCTET | A sequence began with an octet with its 5 highest-order bits all set, which is always invalid in UTF-8. |
k_VALUE_LARGER_THAN_0X10FFFF | A sequence began with an octet with its 5 highest-order bits all set, which is always invalid in UTF-8. |
k_SURROGATE | Illegal occurrence of Unicode code point reserved for surrogate values in UTF-16. Note that all surrogate values are illegal as Unicode code points. |
