EncoderFallbackBuffer.GetNextChar Method ()
When overridden in a derived class, retrieves the next character in the fallback buffer.
Assembly: mscorlib (in mscorlib.dll)
An encoding operation calls the Fallback method if the operation encounters an unknown character or surrogate pair in the input. For example, in the case of a replacement fallback, if the Fallback method returns true, a substitute string exists that can be encoded instead of the unknown input. The encoding operation calls the method repeatedly and obtains the substitute string one character at a time. When all characters in the fallback buffer have been returned to the encoder, the method should return U+0000.
For an exception fallback handler, themethod should return U+0000.
