Utf8Codec constructor
- bool _allowMalformed = false,
Instantiates a new Utf8Codec.
The optional _allowMalformed argument defines how decoder (and decode)
deal with invalid or unterminated character sequences.
If it is true (and not overridden at the method invocation) decode and
the decoder replace invalid (or unterminated) octet
sequences with the Unicode Replacement character U+FFFD (�). Otherwise
they throw a FormatException.
Implementation
const Utf8Codec({this._allowMalformed = false});
