 ## Remarks
- The `encoderFallback` and `decoderFallback` parameters are objects that define the fallback strategy used in the event that an encoder cannot convert a character to a sequence of bytes or a decoder cannot convert a sequence of bytes to a character. The .NET Framework provides the following fallback mechanisms:

 - Exception fallback. If the `encoderFallback` argument is an instance of <xref:System.Text.EncoderExceptionFallback>, or the `decoderExceptionFallback` argument is an instance of <xref:System.Text.DecoderExceptionFallback>, the encoding method throws an exception if characters cannot be encoded, and the decoding method throws an exception if a byte sequence cannot be decoded.

-          <para>Because calls to this method use your implementation of the <see cref="M:System.Text.EncodingProvider.GetEncoding(System.String)" /> method, you do not have to override it. When user code attempts to retrieve an encoding by calling the <see cref="M:System.Text.EncodingProvider.GetEncoding(System.String,System.Text.EncoderFallback,System.Text.DecoderFallback)" /> method, the method passes the <paramref name="codepage" /> identifier to every registered encoding provider until one returns a valid encoding. If none returns a valid encoding, the <see cref="M:System.Text.Encoding.GetEncoding(System.Int32)" /> method attempts to retrieve a cached encoding whose code page identifier is <paramref name="codepage" />. Because of this, if you do choose to override the <see cref="M:System.Text.EncodingProvider.GetEncoding(System.Int32,System.Text.EncoderFallback,System.Text.DecoderFallback)" /> method, your override should return <see langword="null" /> if <paramref name="codepage" /> is not the code page identifier of an encoding that you support; it should never throw an exception.</para>
