Utf8Decoder class

Provides an iterator of Unicode codepoints from UTF-8 encoded bytes. The parameters can set an offset into a list of bytes (as int), limit the length of the values to be decoded, and override the default Unicode replacement character. Set the replacementCharacter to null to throw an ArgumentError rather than replace the bad value. The return value from this method can be used as an Iterable (e.g. in a for-loop).
