Replacement Fallback Buffer Class
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Represents a substitute input string that is used when the original input character cannot be encoded. This class cannot be inherited.

It might not be possible to convert a character to an equivalent encoded byte sequence if no suitable encoding exists. A common reason for an encoding to fail is if the conversion operation uses a code page that cannot represent the character to encode.
If the input character cannot be converted to an output byte sequence, a System.Text.EncoderReplacementFallback object provides a replacement string that is substituted for the original input character. The replacement string initializes the value of the EncoderReplacementFallback object, and the value of the EncoderReplacementFallback object initializes the value of an EncoderReplacementFallbackBuffer object. The value of an EncoderReplacementFallbackBuffer object is called the replacement fallback buffer. The conversion operation encodes the replacement fallback buffer instead of the original input character, then continues to process the remainder of the input.
Gets the number of characters in the replacement fallback buffer that remain to be processed.
Determines whether the specified object is equal to the current object.(Inherited from Object)
|Fallback(Char, Char, Int32)||
Indicates whether a replacement string can be used when an input surrogate pair cannot be encoded, or whether the surrogate pair can be ignored. Parameters specify the surrogate pair and the index position of the pair in the input.
Prepares the replacement fallback buffer to use the current replacement string.
Serves as the default hash function.(Inherited from Object)
Retrieves the next character in the replacement fallback buffer.
Gets the Type of the current instance.(Inherited from Object)
Creates a shallow copy of the current Object.(Inherited from Object)
Causes the next call to the GetNextChar() method to access the character position in the replacement fallback buffer prior to the current character position.
Initializes all internal state information and data in this instance of EncoderReplacementFallbackBuffer.
Returns a string that represents the current object.(Inherited from Object)
