Utf8Codec constructor
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({bool allowMalformed = false})
: _allowMalformed = allowMalformed;
