Replace invalid utf-32 characters with U+FFFD � REPLACEMENT CHARACTER (0xFFFD)

[nikas-belogolov]

Describe the bug We need to replace invalid utf-32 characters with the Replacement Character

Expected behavior The expected behavior is to replace invalid utf-32 characters with the Replacement Character

Additional context The Replacement Character is used to replace invalid characters. Golang do that in their JSON standard library

Maybe something like this: int.TryParse(source.Substring(index, 4), NumberStyles.HexNumber, CultureInfo.InvariantCulture, out int hex) if (!hex.IsValidUtf32CodePoint()) hex = 0xFFFD;

Thanks for the suggestion, but I'm not sure that this behavior is in line with JSON.

Lastly, this project is no longer active.
