System::Text::EncoderFallbackBuffer Class Referenceabstract

Provides buffer for fallback implementation. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument. More...

Inherits System::Object.

)
pure virtual

Implements actual fallback procedure.

Parameters
charUnknownHighHigh part of surrogate pair that triggered error.
charUnknownLowLow part of surrogate pair that triggered error.
indexIndex of character that triggered error.
Returns
True if buffer processes unknown characters, false if it ignores them.
