Represents the text encoding that the caller uses to process the output.
Providing an EncodingType is recommended because the API provides the
beginning offsets for various outputs, such as tokens and mentions, and
languages that natively use different text encodings may access offsets
differently.
If EncodingType is not specified, encoding-dependent information (such as
begin_offset) will be set at -1.
Utf16
Encoding-dependent information (such as begin_offset) is calculated based
on the UTF-16 encoding of the input. Java and JavaScript are examples of
languages that use this encoding natively.
Utf32
Encoding-dependent information (such as begin_offset) is calculated based
on the UTF-32 encoding of the input. Python is an example of a language
that uses this encoding natively.
Utf8
Encoding-dependent information (such as begin_offset) is calculated based
on the UTF-8 encoding of the input. C++ and Go are examples of languages
that use this encoding natively.
