This annotation marks the experimental API for encoding and decoding between binary data and printable ASCII character sequences.
Beware using the annotated API especially if you're developing a library, since your library might become binary incompatible with the future versions of the standard library.
Any usage of a declaration annotated with
@ExperimentalEncodingApi must be accepted either by
annotating that usage with the OptIn annotation, e.g.
or by using the compiler argument
