This class sets the extended channel interpretation mode indicator for the utf8 character set. While this is a Data object, it does not directly encode data. Instead, it sets a flag in the data stream which tells a decoder how to interpret the data that follows. Utf8 is a widely supported character set, so this may be a good choice if you need to encode characters that are not supported in alphanumeric mode. Note that JavaScript strings do not use utf8 characters. This module does not provide the functionality required to convert characters to utf8.
