# Utf8Codec constructor Null safety

const Utf8Codec(

1. {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({bool allowMalformed = false})
        : _allowMalformed = allowMalformed;
